Drayton Valley 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 1971 to 1993.
The Drayton Valley electoral district was formed from the Stony Plain, Leduc, Edson, and Wetaskwin electoral districts prior to the 1930 Alberta general election. The Drayton Valley electoral district would be abolished and the Drayton Valley-Calmar electoral district would be formed in its place prior to the 1993 Alberta general election.
