2019 Prince Edward Island general election

The 2019 Prince Edward Island general election was held to elect the members of the 66th General Assembly of Prince Edward Island. The vote in 26 of the 27 districts was held on 23 April 2019, while the vote for the member from Charlottetown-Hillsborough Park was deferred to 15 July due to the death of the Green Party's candidate. However, Charlottetown-Hillsborough Park still voted in a referendum on electoral reform. Natalie Jameson won the deferred election in the district.

The Progressive Conservatives under new leader Dennis King won thirteen seats (including the deferred seat) to form a minority government. The Greens under leader Peter Bevan-Baker won eight seats to form the Official Opposition. The Liberals under Premier Wade MacLauchlan were reduced to six seats and MacLauchlan lost in his own district. The Progressive Conservatives' share of the popular vote was steady at 37%, the Green Party enjoyed a 20 point increase to 31%, and the Liberals' share dropped 11 points to 30%. The Greens won several seats in or near the two cities of Charlottetown and Summerside, while the Progressive Conservatives took several more rural seats from the Liberals. The result was considered a major political upset, as the Progressive Conservatives won a plurality of the popular vote and came within one seat of an outright majority in the legislative assembly despite having not lead in any opinion polls since the previous provincial election, and polling had generally indicated the race to be between the Greens and the Liberals; a few polls taken in the weeks prior to the election had seen the Progressive Conservatives move into second place ahead of the Liberals, but even then the polls had consistently predicted a Green victory.

A referendum on electoral reform that asked Islanders if they wished to adopt a mixed-member proportional representation voting system was held in conjunction with the election. The initiative failed to pass in at least 60% of the districts as required under provincial legislation to proceed so the province did not change from the first past the post system in subsequent elections. As well, the Island-wide popular vote showed about 51% of voters voted to stay with the current first-past-the-post voting system while about 49% voted for the proposed change.

The election was the first time since the 1890 Prince Edward Island general election that the province elected a minority government, the first time in the province's history that a significant number of voters turned to a third party besides the dominant Liberals and Progressive Conservatives, and the first time that a Green Party reached official opposition status in any Canadian provincial legislature.
