# List of Prince Edward Island by-elections

The list of Prince Edward Island by-elections includes every by-election held in the Canadian province of Prince Edward Island since 1873. 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 the legislative assembly. Until 1932 incumbent members were required to recontest their seats upon being appointed to Cabinet. Nearly all of these Ministerial by-elections were uncontested.
