The Stz'uminus First Nation (formerly known as the Chemainus Indian Band and Chemainus First Nation) is a First Nations government located in southeastern Vancouver Island, British Columbia, Canada, near the town of Ladysmith, British Columbia. The Stz'uminus First Nation is a member government of the Naut'sa mawt Tribal Council. In early 2009, chief and council unanimously passed a band council resolution to officially change the name from Chemainus to Stz'uminus in order to reflect its original Hul'qumi'num language name.
