Quamichan (or Kw’amutsun) is a traditional nation of the Coast Salish people, commonly referred to by the English adaptation of Qu'wutsun as the Cowichan Indians, or First Nations, of the Cowichan Valley on Vancouver Island, in the area of the city of Duncan, British Columbia. In 1909, there were reported to be 260 people living in the village.
The Quamichan are now part of the Cowichan Tribes First Nation, along with several other Cowichan-area peoples.
