Squamish is a Coast Salish language spoken by the Squamish people of the Pacific Northwest. It is spoken in southwestern British Columbia, Canada, centred on their reserve communities in Squamish, North Vancouver, and West Vancouver. An archaic historical rendering of the native Sḵwx̱wú7mesh is Sko-ko-mish but this should not be confused with the name of the Skokomish people of Washington state. Squamish is most closely related to the Sechelt, Halkomelem, and Nooksack languages.

In 2012, there was population of 3,893 band members registered with the Squamish Nation.

The traditional territory is in the area now in southwestern British Columbia, Canada, and covers Point Grey as the southern border. From here, it continues northward to Roberts Creek on the Sunshine Coast, up the Howe Sound. The northern part includes the Squamish, Cheakamus, Elaho and Mamquam rivers. Up the Cheakamus River it includes land past Whistler, British Columbia. The southern and eastern part of their territory includes Indian Arm, along Burrard Inlet, through False Creek then English Bay and Point Grey.
