Innisfail was a provincial electoral district in Alberta, Canada, mandated to return a single member to the Legislative Assembly of Alberta from 1905 to 1940 and again from 1971 to 1993.

The electoral district was named for the Town of Innisfail in central Alberta.

The first Member of the Legislative Assembly for Innisfail was John A. Simpson who had been originally elected in the 1902 Northwest Territories general election to the Innisfail seat in the 5th North-West Legislative Assembly prior to Confederation of Alberta.

Prior to the 1940 Alberta general election Innisfail was split between Rocky Mountain House and Red Deer electoral districts.

The returning officer, appointed by Rutherford, broke the tie by giving his vote to the Liberal candidate.
