List of Alberta by-elections

The list of Alberta by-elections includes every by-election held in the Canadian province of Alberta. By-elections occur whenever there is a vacancy in the Legislative Assembly, although an imminent general election may allow the vacancy to remain until the dissolution of parliament. Until 1926 incumbent members were required to recontest their seats upon being appointed to Cabinet. These Ministerial by-elections were almost always uncontested.
