Prince Edward Island Liberal Party

The Prince Edward Island Liberal Party, officially the Prince Edward Island Liberal Association, is a political party in the province of Prince Edward Island, Canada. It is one of the three parties currently represented in the Legislative Assembly of Prince Edward Island, and along with its primary rival the Conservative Party of PEI, one of only two parties with continual presence in the provincial legislature since confederation.

The PEI Liberals has formed the government of Prince Edward Island for 90 of the approximately 160 years since PEI became a province of Canada. It has produced 21 of the province's 34 premiers, including:

• Canada's youngest Premier (Alex Campbell, 32 years and 8 months in 1966, a record to be broken by New Brunswick's Brian Gallant who became premier in 2014 at age 32 years and 5 months)
• Canada's first and third premiers of non-European descent (Joe Ghiz upon winning the 1986 election, and his son Robert Ghiz became the third upon winning the 2007 election)
• Canada's first female premier with an elected mandate (Catherine Callbeck in 1993)
• Canada's second gay premier (Premier Wade MacLauchlan in 2015, second to Ontario's Kathleen Wynne).

Prior to 2017, the party and its counterparts in Newfoundland and Labrador, Nova Scotia, and New Brunswick were formally the provincial branches of the Liberal Party of Canada. The national party ended its confederated organizational model in 2016 and severed formal governance relationship with all provincial liberal parties. The PEI Liberal Party (along with the Nova Scotia Liberal Party) has however continued its formal affiliation with the national party by amending the governance and membership provisions in its constitution to align them with applicable rules and requirements of the national party, create overlapping governance organizational and administrative structures for both entities.
