The Coast Salish is a group of ethnically and linguistically related Indigenous peoples of the Pacific Northwest Coast, living in the Canadian province of British Columbia and the U.S. states of Washington and Oregon. They speak one of the Coast Salish languages. The Nuxalk (Bella Coola) nation are usually included in the group, although their language is more closely related to Interior Salish languages.

The Coast Salish are a large, loose grouping of many nations with numerous distinct cultures and languages. The Coast Salish cultures differ considerably from those of their northern neighbors. They have a patrilineal and matrilineal kinship system, with inheritance and descent passed through the male and female line.
