Havasupai is a dialect of the Upland Yuman language spoken by fewer than 450 people on the Havasupai Indian Reservation at the bottom of the Grand Canyon. It is the only Native American language in the United States of America spoken by 100% of its indigenous population. As of 2005, Havasupai remained the first language of residents of Supai Village, the tribal government seat.
The Havasupai dialect is nearly identical to the dialect of the Hualapai, although the two groups are socially and politically distinct (Kendall 1983:5). It is a little more distantly related to the Yavapai dialects. Grammatical descriptions, vocabularies, and texts documenting Havasupai have been published (Mithun 1999:578).
As of 2004, "a Wycliffe Bible Translators project ... under way to translate the Old and the New Testaments into the Havasupai language" was progressing slowly.
