The 2021 Nova Scotia general election was held on August 17, 2021, to elect members to the 64th General Assembly of Nova Scotia.

In a major upset, Tim Houston led the Progressive Conservatives to power for the first time since 2006, and with a majority government for the first time since 1999. With a popular vote share of 38.44%, the PCs won the smallest winning vote share of any majority government in Nova Scotian electoral history, and won nearly twice the number of seats as the Liberals, despite their overall vote share differing by less than 2%.

Elizabeth Smith-McCrossin’s victory in Cumberland North marked the first occasion since 1988 that an independent candidate won election to the House of Assembly. A record number of four Black Nova Scotians were elected MLAs; prior to this election, only five Black MLAs had ever been elected in Nova Scotia.

Redistribution of ridings In April 2019, the Electoral Boundaries Commission released its report which recommended changing the number of electoral districts from 51 to 55, including reinstating the four former districts of Argyle, Clare, Preston and Richmond. In October 2019, the Nova Scotia Legislature passed implementing legislation, providing for the following changes to take effect at the forthcoming election.
