Havasupai–Hualapai (Havasupai–Walapai) is the Native American language spoken by the Hualapai (Walapai) and Havasupai peoples of northwestern Arizona. It is closely related to the Yavapai language.
Havasupai–Hualapai belongs to the Pai branch of the Yuman language family, together with Yavapai and Paipai, which is spoken in northern Baja California. The two groups have separate sociopolitical identities, but a consensus among linguists is that the differences in speech among them lie only at the dialect level, rather than constituting separate languages (Campbell 1997:127; Goddard 1996:7; Kendall 1983:5-7; Mithun 1999:577-578). The Havasupai and Hualapai report that they speak the same language, and indeed the differences between their dialects have been reported as "negligible" (Kozlowski 1976:140).
