Proposals linking Chimariko to other languages in various versions of the hypothetical Hokan family have been advanced. Roland Dixon suggested a relationship between Chimariko and the Shastan and Palaihnihan families. Edward Sapir's famous 1929 classification grouped Chimariko with Shastan, Palaihnihan, Pomoan, and the Karuk and Yana languages in a Hokan sub-grouping known as Northern Hokan. A Kahi family consisting of Chimariko, Shastan, Palaihnihan, and Karuk has been suggested (appearing also within Sapir's 1929 Northern Hokan). Most specialists currently find these relationships to be undemonstrated, and consider Chimariko to remain best considered an isolate.
