The Cupan languages are a branch of the Uto-Aztecan language family that comprises Cupeño, Ivilyuat (Cahuilla), Luiseño-Juaneño, and perhaps Nicoleño, all historically spoken in southern California.
The branch had long been considered to be part of the Takic subgroup, but there is doubt about the validity of Takic as a genetic unit, the similarities between the languages classed as Takic possibly being due primarily to borrowing.
