Indigenous Languages of Oaxaca: 16 Language Families & Where They're Spoken

Oaxaca is the most linguistically diverse state in Mexico. With at least 16 indigenous languages — and dozens of regional variants — spoken across its eight regions, no other Mexican state comes close. According to Mexico’s National Institute of Indigenous Languages (INALI), Oaxaca accounts for nearly a quarter of the country’s 68 recognized indigenous languages. Each one carries centuries of accumulated knowledge about medicine, agriculture, astronomy, and the natural world.

This guide covers every major indigenous language spoken in Oaxaca: the language families they belong to, where they are spoken, how many people speak them, their UNESCO endangerment status, and what is being done to keep them alive.

Why Indigenous Languages Matter

A language is far more than a communication tool. It encodes a community’s entire way of understanding the world — concepts, relationships, and categories of experience that may not exist in any other language.

Consider a few examples from around the world: the Inuit languages have dozens of words for variations of snow and ice because those distinctions are essential for survival. Portuguese has saudade, a word for a specific kind of nostalgic longing that has no direct equivalent in English. Japanese has kuchisabishii, the feeling of eating not from hunger but because “your mouth feels lonely.” Mexican Spanish itself uses naras, a word for a particular kind of discomfort or unease.

The indigenous languages of Oaxaca contain their own rich vocabularies for concepts tied to local ecology, social organization, spiritual practice, and daily life. When a language disappears, those concepts — and the worldview they represent — disappear with it.

The Role of Language in Oaxacan Identity

In many Oaxacan communities, an indigenous language is a child’s first language — the medium through which they learn to name the world, express emotions, and understand their place in the community. These languages are inseparable from Oaxaca’s cultural expressions: the songs performed at festivals, the oral histories recounted by elders, the names given to mountains, rivers, and towns, and the specialized vocabulary used in traditional crafts, agriculture, and cooking.

Language is also a marker of belonging. Speaking Zapotec, Mixtec, or Mazatec connects a person to a specific community, region, and cultural lineage that stretches back thousands of years.

How Indigenous Languages Are Classified

INALI uses a three-tier classification system to organize Mexico’s indigenous languages:

Family > Group > Language

Families and groups are organized according to shared linguistic characteristics — grammar, phonology, and vocabulary patterns that indicate historical relationships between languages. Within each language, there are also regional variants (sometimes called dialects). Some linguists argue that many of these variants are distinct enough to be considered separate languages in their own right, though no official consensus has been reached.

In total, Mexico recognizes 68 indigenous languages. Oaxaca is home to 15-16 of them (depending on the classification used), belonging to five language families.

The 16 Indigenous Languages of Oaxaca

The following data draws from INALI’s catalog and Mexico’s Cultural Information System (SIC). Speaker counts are approximate and based on census data; actual numbers may be higher, as census counts tend to undercount indigenous language speakers.

Oto-Manguean Family

The Oto-Manguean family is the largest and most diverse language family in Oaxaca. It includes the following languages:

Zapotec (Zapoteco)

Variants: 62
Speakers: approximately 490,000
Where spoken: Central Valleys (Tlacolula, Ocotlan, Zaachila), Sierra Norte (Sierra Juarez), Isthmus of Tehuantepec (Juchitan, Tehuantepec)
Endangerment: Several variants are classified as vulnerable or definitely endangered by UNESCO. Valley Zapotec variants tend to have the most speakers; some Sierra variants have fewer than 1,000 speakers.

Zapotec is one of the oldest documented languages in the Americas. The ancient Zapotecs developed a writing system at Monte Alban around 500 BCE, making it one of the earliest writing systems in Mesoamerica. Today, Zapotec has enormous dialectal diversity — speakers from the Central Valleys, the Sierra Norte, and the Isthmus of Tehuantepec may not understand each other. Each variant carries its own oral literature, poetry, and place-name traditions.

Mixtec (Mixteco)

Variants: 81
Speakers: approximately 517,000
Where spoken: Mixteca Alta (Tlaxiaco, Nochixtlan), Mixteca Baja (Huajuapan de Leon, Silacayoapan), Mixteca de la Costa (Jamiltepec, Pinotepa Nacional). Also spoken in neighboring Puebla and Guerrero, and by large diaspora communities in Mexico City and the United States.
Endangerment: Several variants are classified as definitely endangered or severely endangered by UNESCO.

Mixtec has more recognized variants than any other indigenous language in Mexico. The Mixtec people call themselves uu Savi (“People of the Rain”) and their language has a rich tradition of pictographic codices — pre-Hispanic manuscripts that record history, genealogy, and mythology. Mixtec communities in the United States (particularly California and New York) have created cross-border language preservation networks.

Mazatec (Mazateco)

Variants: 16
Speakers: approximately 230,000
Where spoken: Sierra Mazateca in northern Oaxaca (Huautla de Jimenez, Jalapa de Diaz, San Jose Tenango)
Endangerment: Some variants are classified as vulnerable by UNESCO.

The Mazatec language is notable for its “whistled speech” — a system in which speakers communicate using whistled tones that mirror the language’s tonal patterns. This allows communication across mountain valleys without shouting. Huautla de Jimenez, the cultural center of the Mazatec region, is also known for its traditional healing practices, which are conducted in the Mazatec language.

Chinantec (Chinanteco)

Variants: 11
Speakers: approximately 133,000
Where spoken: Northern Oaxaca, particularly the Chinantla region (Valle Nacional, Usila, Ojitlan, Chiltepec)
Endangerment: Some variants are classified as definitely endangered by UNESCO.

Chatino

Variants: 6
Speakers: approximately 51,000
Where spoken: Sierra Madre del Sur in southwestern Oaxaca (Santos Reyes Nopala, San Juan Quiahije, Tataltepec de Valdes)
Endangerment: Some variants are classified as definitely endangered by UNESCO.

Chatino is known among linguists for its complex tonal system — one of the most elaborate tone systems documented in any language worldwide, with some variants using up to 14 distinct tones.

Amuzgo

Variants: 4
Speakers: approximately 57,000
Where spoken: Southwestern Oaxaca and neighboring Guerrero (San Pedro Amuzgos, Santa Maria Ipalapa)
Endangerment: Classified as vulnerable by UNESCO.

Amuzgo communities are renowned for their backstrap-loom weaving. The intricate textile patterns have names and meanings described in the Amuzgo language.

Triqui

Variants: 4
Speakers: approximately 29,000
Where spoken: Mixteca region (San Juan Copala, San Andres Chicahuaxtla, Santo Domingo del Estado)
Endangerment: Classified as definitely endangered by UNESCO.

Triqui is one of the most tonal languages in the world, with some analyses identifying up to eight distinct tones. Triqui women are known for their distinctive red huipiles (traditional blouses) woven with geometric patterns, each with culturally specific names in the Triqui language.

Cuicatec (Cuicateco)

Variants: 3
Speakers: approximately 13,000
Where spoken: Canada region of northern Oaxaca (Cuicatlan, Teutila, Tepeuxila)
Endangerment: Classified as definitely endangered by UNESCO.

Ixcatec (Ixcateco)

Variants: 1 (no recognized variants)
Speakers: fewer than 10 (critically endangered)
Where spoken: Santa Maria Ixcatlan in the Mixteca region
Endangerment: Classified as critically endangered by UNESCO. Ixcatec is one of the most endangered languages in Mexico, with only a handful of elderly speakers remaining.

Chocholtec (Chocholteco / Ngigua)

Variants: 3
Speakers: approximately 700
Where spoken: Mixteca Alta (Coixtlahuaca, Tepelmeme de Morelos, San Miguel Tulancingo)
Endangerment: Classified as severely endangered by UNESCO.

Mixe-Zoquean Family

Mixe (Ayuuk)

Variants: 6
Speakers: approximately 136,000
Where spoken: Sierra Mixe in northeastern Oaxaca (Tlahuitoltepec, Ayutla, Totontepec, Tamazulapam)
Endangerment: Some variants are classified as vulnerable by UNESCO.

The Mixe people call themselves Ayuuk jaa’y (“People of the Word”) and their language Ayuuk. Mixe communities have a strong tradition of brass-band music, and the town of Tlahuitoltepec is famous throughout Mexico for its community music education programs. The Mixe language plays a central role in the communal governance system (usos y costumbres) practiced in Mixe towns.

Zoque

Variants: 2
Speakers: approximately 68,000
Where spoken: Western Oaxaca, near the border with Chiapas (Santa Maria Chimalapa, San Miguel Chimalapa)
Endangerment: Classified as definitely endangered by UNESCO.

The Chimalapas region, where Oaxacan Zoque is spoken, contains one of the largest remaining tracts of tropical rainforest in Mexico.

Yuto-Nahua Family

Nahuatl

Variants: 8 (in Oaxaca)
Speakers: approximately 12,000-13,000 in Oaxaca (over 1.7 million nationwide)
Where spoken: Northern Oaxaca, near the borders with Puebla and Veracruz
Endangerment: Oaxacan Nahuatl variants are classified as definitely endangered by UNESCO, though the language as a whole is not endangered nationally.

Nahuatl is the most widely spoken indigenous language in Mexico overall, but its presence in Oaxaca is relatively small compared to the Oto-Manguean languages. Many common Mexican Spanish words — chocolate, tomate, aguacate, mezcal — come from Nahuatl.

Language Isolates

Two languages spoken in Oaxaca do not belong to any known language family:

Huave (Ombeayiuts)

Variants: 2
Speakers: approximately 18,000
Where spoken: Pacific coast lagoon towns on the Isthmus of Tehuantepec (San Mateo del Mar, San Dionisio del Mar, San Francisco del Mar, Santa Maria del Mar)
Endangerment: Classified as definitely endangered by UNESCO.

The Huave people are traditionally fishermen and their language contains a rich vocabulary related to lagoon ecosystems, wind patterns, and fishing techniques. They call themselves Ikoots (“Us”) and their language Ombeayiuts (“Our Language”).

Chontal of Oaxaca (Slijuala Xanuk’)

Variants: 2
Speakers: approximately 4,600
Where spoken: Southern Oaxaca, in the coastal mountains near Huatulco (San Pedro Huamelula, Santa Maria Ecatepec)
Endangerment: Classified as severely endangered by UNESCO.

Note: Oaxacan Chontal is entirely unrelated to Chontal of Tabasco, which belongs to the Mayan language family. The shared name is a historical accident — “chontal” comes from the Nahuatl word chontalli, meaning “foreigner.”

Where Each Language Is Spoken: Oaxaca’s Eight Regions

Oaxaca’s indigenous languages map roughly onto its eight geographic and cultural regions:

Central Valleys (Valles Centrales): Zapotec variants dominate, especially around Oaxaca City, Tlacolula, Ocotlan, and Zaachila.
Sierra Norte: Zapotec (Sierra variant), Chinantec, and some Mixe communities.
Sierra Sur: Chatino and Zapotec (Southern Sierra variant).
Mixteca: Mixtec, Triqui, Ixcatec, Chocholtec, and Cuicatec.
Canada: Cuicatec, Mazatec, Nahuatl, and Chinantec.
Papaloapan (Tuxtepec): Chinantec, Mazatec, and Nahuatl.
Isthmus of Tehuantepec: Zapotec (Isthmus variant), Huave, Zoque, and Mixe.
Costa: Mixtec (coastal variant), Chatino, Amuzgo, and Chontal.

UNESCO Endangerment Status

UNESCO’s Atlas of the World’s Languages in Danger classifies languages on a six-level scale: safe, vulnerable, definitely endangered, severely endangered, critically endangered, and extinct. According to UNESCO data, a language dies somewhere in the world roughly every two weeks.

In Oaxaca, the situation is as follows:

Status	Languages
Critically endangered	Ixcatec (fewer than 10 speakers)
Severely endangered	Chocholtec, Chontal of Oaxaca
Definitely endangered	Several Zapotec variants, several Mixtec variants, Chinantec, Chatino, Triqui, Cuicatec, Huave, Zoque, Oaxacan Nahuatl
Vulnerable	Mazatec, Mixe, Amuzgo, other Zapotec and Mixtec variants

The primary factors driving language loss in Oaxaca are:

Migration: Young people move to cities (Oaxaca City, Mexico City, Puebla) or to the United States for economic opportunities. In urban and diaspora settings, Spanish or English becomes the dominant daily language.
Educational policy: For most of the 20th century, Mexican public education was conducted exclusively in Spanish. Indigenous-language speakers were punished for using their languages at school. Although this policy has changed, its effects persist across generations.
Social stigma: Speaking an indigenous language has historically been associated with poverty and low social status in Mexican society. Many parents chose not to teach their children in order to spare them discrimination.
Media dominance: Television, radio, internet, and social media are overwhelmingly in Spanish, reducing the everyday contexts in which indigenous languages are used.

Basic Phrases in Zapotec and Mixtec

Learning even a few words in a local indigenous language is a meaningful way to show respect when visiting Oaxacan communities. Here are some basic phrases. Note that pronunciation varies significantly by region and variant.

Zapotec (Isthmus variant / Diidxaza)

English	Zapotec
Hello	Padiuxhi
Thank you	Xquixe pe
How are you?	Xinh lii?
Yes	Aaa
No	Yanna
Water	Nisa
Please	Nagasi

Mixtec (general examples; varies widely by variant)

English	Mixtec
Hello	Naa na
Thank you	Tasi
How are you?	Nasa iya ni?
Yes	Han
No	Ama
Water	Ndute
Good	Vaha

These are approximate representations. Zapotec and Mixtec are tonal languages, and meaning can change depending on pitch. If you want to learn more, ask local speakers — most people are delighted when visitors show genuine interest in their language.

Efforts to Preserve Indigenous Languages

Government Programs

Mexico’s federal government and the state of Oaxaca have taken several steps to support indigenous languages:

INALI (National Institute of Indigenous Languages): Created in 2003, INALI is responsible for cataloging, promoting, and defending indigenous languages. It has published dictionaries, grammars, and educational materials in multiple Oaxacan languages.
General Law on the Linguistic Rights of Indigenous Peoples (2003): This federal law recognizes indigenous languages as “national languages” with the same validity as Spanish for all purposes of government and public services. Indigenous-language speakers have the right to use their language in legal proceedings, education, and interactions with government agencies.
Bilingual and intercultural education: The Mexican education system now includes bilingual schools in indigenous communities, though implementation is uneven. Teacher training in indigenous languages remains insufficient, and many bilingual schools still prioritize Spanish.
International Mother Language Day (February 21): Mexico officially commemorates this UNESCO-designated day, and Oaxacan communities organize events to celebrate their linguistic heritage.

Community and NGO Initiatives

The most effective language preservation work in Oaxaca often comes from communities themselves:

Language nests (nidos de lenguas): Preschool programs where children are immersed entirely in an indigenous language, modeled after successful Maori and Hawaiian language revitalization programs. Several Zapotec and Mixtec communities have established these.
Community documentation projects: Speakers collaborate with linguists to create written records, audio archives, and video documentaries of their languages, particularly for variants with few remaining speakers.
Digital platforms: Apps, websites, YouTube channels, and social media accounts dedicated to teaching and practicing Oaxacan indigenous languages have grown significantly. Some communities have created localized keyboards and predictive text for their languages.
Cultural festivals: Events like the Guelaguetza, community patron saint festivals, and regional ferias often include indigenous-language performances, oratory contests, and poetry readings.
Radio stations: Community radio stations broadcasting in indigenous languages (such as Radio Jenpoj in the Mixe region and Radio Calenda in the Central Valleys) provide daily exposure to these languages in their home communities.

How Tourists Can Respectfully Engage with Indigenous Languages

If you visit Oaxaca and want to show respect for its linguistic diversity, here are some practical suggestions:

Learn basic greetings. Even saying “hello” or “thank you” in the local indigenous language is appreciated. Ask your guide, host, or a community member to teach you a few words.
Ask before recording. If you hear people speaking an indigenous language and want to record it (audio or video), always ask permission first. These languages are part of living cultures, not curiosities to be collected.
Visit community language projects. Some communities welcome visitors to cultural centers, language workshops, or bilingual schools. The Oaxaca Lending Library and the Centro Academico y Cultural San Pablo in Oaxaca City sometimes host language-related events.
Buy from indigenous-language speakers. When shopping at markets or visiting artisan workshops, your purchase directly supports families that are maintaining their languages and cultural traditions.
Avoid treating indigenous languages as extinct or quaint. These are living languages spoken by real communities in their daily lives. Phrases like “I heard they still speak…” or “Is that a real language?” can be unintentionally dismissive.
Support language-related organizations. Organizations working on Oaxacan language preservation include INALI, the Oaxacan Institute of Cultures (IOCIO), and various community-based nonprofits.

Frequently Asked Questions

How many indigenous languages are spoken in Oaxaca?

Between 15 and 16, depending on the classification system used. INALI recognizes 15 indigenous languages in Oaxaca. When regional variants are counted, the number rises to over 170 distinct linguistic varieties.

What is the most spoken indigenous language in Oaxaca?

Mixtec and Zapotec are the two most widely spoken, each with roughly 490,000-520,000 speakers. Together, they account for the majority of indigenous-language speakers in the state. Mazatec is the third most spoken, with approximately 230,000 speakers.

Are Oaxaca’s indigenous languages in danger?

Yes, many are. Ixcatec has fewer than 10 speakers remaining and will likely become extinct within a generation. Chocholtec and Chontal of Oaxaca are severely endangered. Even languages with large speaker populations, like Zapotec and Mixtec, have individual variants that are critically or severely endangered, especially in communities where younger generations have shifted to Spanish.

What is INALI?

INALI is Mexico’s National Institute of Indigenous Languages (Instituto Nacional de Lenguas Indigenas), created in 2003. It catalogs Mexico’s indigenous languages, promotes their use, and defends the linguistic rights of indigenous speakers.

Can I learn an indigenous language of Oaxaca?

Yes, though resources vary by language. For Zapotec and Mixtec, there are online courses, YouTube channels, dictionaries, and language-learning apps. For less-documented languages, the best approach is community-based learning. Universities in Oaxaca (such as UABJO) and cultural organizations sometimes offer courses. The Smithsonian’s Recovering Voices program and the Endangered Languages Project also have resources.

What is the difference between a language, a variant, and a dialect?

In INALI’s classification, a “language” is a broad category (e.g., Zapotec), while a “variant” refers to regional forms that may differ significantly in pronunciation, vocabulary, and grammar. The term “dialect” is sometimes used colloquially but can carry negative connotations, implying a variant is less legitimate than a “language.” Many linguists and indigenous communities prefer the term “variant” or advocate for each variant to be recognized as a language in its own right.

Why does Oaxaca have so many indigenous languages?

Oaxaca’s mountainous terrain created natural barriers between communities, allowing languages to develop independently over thousands of years. The state’s complex geography — with deep valleys, high mountain ranges, and isolated coastal areas — fostered linguistic diversification that is unusual even by global standards.

How do indigenous languages help preserve cultural diversity?

Indigenous languages are the primary vehicles for oral traditions, ancestral knowledge, traditional medicine, agricultural practices, and community governance systems. When a language disappears, the specific knowledge encoded in it — including ecological knowledge, historical narratives, and cultural practices — is lost permanently. Protecting these languages means protecting entire systems of knowledge and cultural identity.

How can I contribute to preserving Oaxaca’s indigenous languages?

You can learn about these languages and share what you learn with others. You can support organizations working on language preservation through donations or volunteer work. When visiting Oaxaca, you can patronize businesses run by indigenous-language-speaking communities. You can also advocate for policies that support bilingual education and indigenous language rights.
