The Cariban languages are a family of languages Indigenous to north-eastern South America. They are widespread across northernmost South America, from the mouth of the Amazon River to the Colombian Andes, and they are also spoken in small pockets of central Brazil. The languages of the Cariban family are relatively closely related. There are about three dozen, but most are spoken only by a few hundred people. Macushi is the only language among them with numerous speakers, estimated at 30,000. The Cariban family is well known among linguists partly because one language in the family—Hixkaryana—has a default word order of object–verb–subject. Prior to their discovery of this, linguists presumed that this order did not exist in any spoken natural language.

Genetic relations The Cariban languages share irregular morphology with the Jê and Tupian families. Ribeiro connects them all in a Je–Tupi–Carib family. Meira, Gildea, & Hoff (2010) note that likely morphemes in proto-Tupian and proto-Cariban are good candidates for being cognates, but that work so far is insufficient to make definitive statements.

Language contact Jolkesky (2016) notes that there are lexical similarities with the Guato, Kawapana, Nambikwara, Taruma, Warao, Arawak, Bororo, Jeoromitxi, Karaja, Rikbaktsa, and Tupi language families due to contact.

Extensive lexical similarities between Cariban and various Macro-Jê languages suggest that Cariban languages had originated in the Lower Amazon region (rather than in the Guiana Highlands). There they were in contact with early forms of Macro-Jê languages, which were likely spoken in an area between the Parecis Plateau and upper Araguaia River.

Family division The Cariban languages are closely related. In many cases where one of the languages is more distinct, this is due to influence from neighboring languages rather than an indication that it is not closely related. According to Kaufman (2007), "Except for Opon, Yukpa, Pimenteira and Palmela (and possibly Panare), the Cariban languages are not very diverse phonologically and lexically (though more so than Romance, for example)."Kaufman, Terrence. 2007. "South America". In: R. E. Asher and Christopher Moseley (eds.), Atlas of the World’s Languages (2nd edition), 59–94. London: Routledge.

Previous classifications Good data had been collected on most Cariban languages by ; classifications prior to that time (including Kaufman 2007, which relies on Kaufman 1994) are unreliable.

Several such classifications have been published; the one shown here, by Derbyshire (1999) divides Cariban into seven branches. A traditional geographic classification into northern and southern branches is cross referenced with (N) or (S) after each language.Desmond Derbyshire, 1999. "Carib". In Dixon & Aikhenvald, eds., The Amazonian Languages. CUP.

The extinct Patagón de Perico language of northern Peru also appears to have been a Cariban language, perhaps close to Carijona. Yao is so poorly attested that Gildea believes it may never be classified.
