Three Hills was a provincial electoral district in Alberta, Canada, mandated to return a single member to the Legislative Assembly of Alberta using the first past the post method of voting from 1963 to 1993.
The Three Hills electoral district was created in the 1963 electoral boundary re-distribution from the Didsbury, Gleichen, and Olds electoral districts. It was abolished in 1993 and merged with Drumheller to form Three Hills-Airdrie, which would last only one session before redistribution.
Three Hills is named for the town of Three Hills, Alberta.
