# List of Saskatchewan by-elections

The list of Saskatchewan by-elections includes every by-election held in the Canadian province of Saskatchewan. 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.

## Causes

A by-election occurs whenever there is a vacancy in the Saskatchewan legislature. Vacancies can occur for the following reasons:
* Death of a member.
* Resignation of a member.
* Voided results
* Expulsion from the legislature.
* Ineligibility to sit.
* Appointment to the cabinet. Incumbent members were required to recontest their seats upon being appointed to Cabinet. These Ministerial by-elections were almost always uncontested. This requirement was amended in 1930 to exempt members if they were appointed within six months of a general election. This requirement was abolished completely in 1936.
