List of Newfoundland and Labrador by-elections

The list of Newfoundland and Labrador by-elections includes every by-election held in the Canadian province of Newfoundland and Labrador. By-elections occur whenever there is a vacancy in the House of Assembly, although an imminent general election may allow the vacancy to remain until the dissolution of parliament. Starting in 1862 incumbent members were required to recontest their seats upon being appointed to Cabinet. This requirement was temporarily abolished due to World War I in 1917 and was permanently abolished in 1928. These Ministerial by-elections were almost always uncontested.
