Banff-Kananaskis is a provincial electoral district in Alberta, Canada.

The district is located in Alberta's Rocky Mountains and the adjacent foothills west of Calgary.

Stretching east to Calgary's border, some farming communities are also included, as well as the Treaty 7 communities of the Tsuu T'ina Nation and the Îyârhe Nakoda's Stoney Reserves.

The district was created in 2017 when the Electoral Boundaries Commission recommended moving the city of Cochrane to the new riding of Airdrie-Cochrane, requiring a new name for Banff-Cochrane.

The district gained small areas to the south and west from Airdrie, Chestermere-Rocky View and Livingstone-Macleod, including the entirety of Kananaskis Country.
