The Champagne and Aishihik First Nations (CAFN) is a First Nation in the Yukon Territory in Canada. Its original population centres were Champagne and Aishihik, but most of its citizens moved to Haines Junction to take advantage of services offered there such as schools. The First Nation government has its main administrative offices there. Other settlements used included Klukshu. Many also live in Whitehorse where the First Nation government has offices. The language originally spoken by the Champagne and Aishihik people was Southern Tutchone.
The Champagne and Aishihik First Nations was one of the first four First Nations to sign a land claims agreement in 1992. The First Nation is also pursuing a land claim in its traditional territory in the northwestern corner of British Columbia.
