Spanish is the de facto official and administrative language of Chile. It is spoken by 99.3% of the population in the form of Chilean Spanish, as well as Andean Spanish. Spanish in Chile is also referred to as "castellano". Although an officially recognized Hispanic language does not exist at the governmental level, the Constitution itself, as well as all official documents, are written in this language.

Indigenous peoples make up 4.58% of the Chilean population according to the 2002 Census, and the major languages of the population are as follows: Mapuche is spoken by an estimated 100,000–200,000 people; Aymara by 20,000 individuals; Quechua by 8,200 individuals; and Rapa Nui by 3,390 people. However, it is not explicit whether all these speakers use the language as their primary language.

According to Law 19253, also known as "The Indigenous Law" (1993), indigenous languages are officially recognized for use and conservation, in addition to Spanish, in the zones in which they are spoken. They can be used for instruction, the promotion of media communication, as names in the Civil Registry, as well as for artistic and cultural promotion.

Bilingual programs in areas occupied by indigenous communities are also under development. However, these programs exist only as small, isolated projects dedicated to the maintenance and promotion of indigenous languages, specifically Mapuche and Aymara, both with varying degrees of success.

Indigenous languages of Chile

In Chile, there are 15 different linguistic dialects spoken that could be considered distinct languages. These languages are varied, and in Chile—unlike other Southern American countries—no large linguistic family exists. Therefore, all indigenous languages are isolated or belong to small families of three or four languages.

Indigenous languages currently spoken

• Mapuche: Mainly spoken in the Biobío, Aracuanía, Metropolitan, and Los Ríos regions by around 100,000 to 200,000 people with different levels of linguistic competency. The Chesungun or Huilliche dialect, spoken by only 2,000 Huilliche people in the Los Lagos region, is a divergent dialect that some experts consider a distinct language from Mapuche. 718,000 people of a total Chilean population of 17,574,003 are Mapuche.
• Aymara: Spoken by 20,000 people in the Arica and Parinacota regions of Tarapacá. It is close to Bolivian Aymara.
• Chilean Quechua, one of the varieties of Southern Quechua: Considered identitical to Sub-Bolivian, it is spoken by around 8,200 people in the region between Antofagasta and Bolivia.Within the Peruvian immigrants residing in established big cities, there are also speakers of distinct Quechuan dialects of Peru.
• Rapa Nui: Used by only 3,390 speakers, majority of speakers are of Easter Island, and a few reside in continental cities like Valparaíso or Santiago.

Indigenous languages in danger of extinction

• Kawésqar: Spoken by a dozen people in Puerto Edén.

Extinct indigenous languages

• Cacán: The language was spoken by the Diaguita Pueblo in the North region of Chile.
• Chono: It is conserved in one linguistic registry and is connected to Chiloé and the Guaitecas Islands; it may have been a northern dialect of Kawésqar.
• Gününa këna: Spoken by the Gününa küne or Puelche people.
• Kunza: Spoken by the Atacameño people around San Pedro de Atacama. It disappeared during the 20th century, and only a few hundred words are remembered. Currently, work is being done to recover it.
• Ona: Spoken by the Selk'nam people on the island of Tierra del Fuego, this language disappeared in Chile during the 20th century, and in Argentina during the 21st century.
• Tehuelche: Spoken by the Aonikenk or Tehuelches people, this language disappeared in Chile during the 20th century and is dwindling in Argentina. Extinct in 2019.
• Yaghan: In Puerto Williams, Cristina Calderón, died in 2022, was the last speaker. Calderón created the dictionary for the continuation and survival of the Yaghan language.
