Halchidhoma (Halehadhoma) is a River Yuman language closely related to Maricopa, possibly a dialect of it, formerly spoken by the Halchidhoma people.

Historical records indicate that there once was a separate Halchidhoma language within the Yuman family, in the River Yuman subdivision. Due to war and conflict with European settlers, the Halchidhoma settled in with the Maricopa people, in their current location around Greater Phoenix. The Halchidhoma currently identify themselves with the Maricopa tribe, and many live in Lehi, which is a small community within the Salt River Pima-Maricopa Indian Community on the south banks of the Salt River. They continue to speak what they refer to as the Halchidhoma language.^{[verification needed]}
