The location of Guaycura. Monqui and Pericú are essentially unattested; Cochimí, which is still spoken, is a Yuman language.

Waikuri (Guaycura, Waicura) is an extinct language of southern Baja California spoken by the Waikuri or Guaycura people. The Jesuit priest Baegert documented words, sentences and texts in the language between 1751 and 1768.

Waikuri may be, along with the Yukian and Chumashan languages and other languages of southern Baja such as Pericú, among the oldest languages established in California, before the arrival of speakers of Penutian, Uto-Aztecan, and perhaps even Hokan languages. All are spoken in areas with long-established populations of a distinct physical type.

Baegert's data is analyzed by Raoul Zamponi (2004). On existing evidence, Guaycura appears to be unrelated to the Yuman languages to its north. Some linguists have suggested that it belonged to the widely scattered Hokan phylum of California and Mexico (Gursky 1966; Swadesh 1967); however, the evidence for this seems inconclusive (Laylander 1997; Zamponi 2004; Mixco 2006). William C. Massey (1949) suggested a connection with Pericú, but the latter is too meagerly attested to support a meaningful comparison. Other languages of southern Baja are essentially undocumented, though people have speculated from non-linguistic sources that Monqui (Monquí-Didiú), spoken in a small region around Loreto, may have been a 'Guaicurian' language, as perhaps was Huchití (Uchití), though that may have actually been a variety of Guaycura itself (Golla 2007).

The internal classification of Gauicurian (Waikurian) languages is uncertain. Massey (1949), cited in Campbell (1997:169), gives this tentative classification based on similarity judgments given by colonial-era sources, rather than actual linguistic data.

However, Laylander (1997) and Zamponi (2004) conclude that Waikuri and Pericú are unrelated.
