List of New Brunswick by-elections
The list of New Brunswick by-elections includes every by-election held in the Canadian province of New Brunswick. 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. Between 1842 and 1927 incumbent members were required to recontest their seats upon being appointed to Cabinet. These Ministerial by-elections were almost always uncontested.
