Katukinan (Catuquinan) is a language family consisting of two languages in Brazil, Katukina-Kanamarí and the perhaps moribund Katawixi. It is often not clear which names in the literature, which are generally tribal names and often correspond to dialects, refer to distinct languages. Indeed, they're close enough that some consider them all to be dialects of a single language, Kanamari (Fabre 2005).

Campbell (2012) note that Adelaar "presents reasonably persuasive evidence that Harákmbut and Katukinan are genetically related."^[1]

Jolkesky (2016) notes that there are lexical similarities with the Jivaro, Máku, Mura-Matanawi, Puinave-Nadahup, Taruma, Tupi, Yanomami, and Arawak language families due to contact. This suggests that Katukinan and the language families with which it was in contact with had been earlier spoken within a central Amazon interaction sphere.^[2]

Many ethnic Katukina had shifted to other languages by the time of European contact. Examples are Panoan Katukina and unclassified Katukinaru.

The common suffix dyapa, djapa means 'tribe' or 'clan', for which the varieties are named. Fabre (2005) lists Kanamarí, Txuhuã-djapá, Katukína do Jutaí (Katukina proper), and Katawixi as four attested languages.

Loukotka (1968) lists the following basic vocabulary items for the Catuquinan languages.^[3]
