The
Sobaipuri were one of many indigenous groups occupying
Sonora and what is now
Arizona at the time Europeans first entered the American Southwest. They were a
Piman or O'odham group who occupied southern Arizona and northern Sonora (the
Pimería Alta) in the 15th-19th centuries. They were a subgroup of the O'odham or
Pima, surviving members of which include the residents of San Xavier del Bac which is now part of the
Tohono O'odham Nation and the
Akimel O'odham.
