Cahuilla County, California

Cahuilla County was a proposed county initiated by the residents of eastern Riverside County, California in the 1980s. The proposed county would have included the Coachella Valley including the cities of Palm Springs, Indio, and Palm Desert, and extended to the current county's border at Blythe at the Colorado River. The western border of the county would have included the mountain community of Idyllwild in the San Jacinto Mountains, east of the Hemet area, which would have remained in the rump Riverside County.

Proponents argued at the time that the area was distinct from the western area, commonly known as the Inland Empire and was too far removed from the county seat at Riverside.

The measure was ultimately defeated.
