The Cowichan sweater is a garment created in North America with a distinctly patterned design knitted out of bulky-weighted yarn. It originated during the late 19th century among the Cowichan, a Coast Salish people in British Columbia. Historically also called the Indian sweater or Siwash sweater (a derogatory Chinook word for Indigenous people), the Cowichan people reclaimed the name after the 1950s as a means of emphasizing their claim to the garment. The popularity of the sweater by the mid-1900s thrust Cowichan sweaters into the world of international fashion, where they have been appropriated by non-Indigenous designers. Nevertheless, several knitters from various Coast Salish communities around Vancouver Island and the mainland of British Columbia continue to create and sell authentic sweaters. In 2011, the Canadian government recognized Cowichan knitters and sweaters as nationally and historically significant.
