The British Columbia general election of 1991 was the 35th provincial election in the Province of British Columbia, Canada. It was held to elect members of the Legislative Assembly of British Columbia. The election was called on September 19, 1991, and held on October 17, 1991. The incumbent Social Credit Party of British Columbia, which had been beset by scandals during Bill Vander Zalm's only term as premier, was defeated by the New Democratic Party of Mike Harcourt. Liberal Party leader Gordon Wilson surprised observers by leading his party to winning one-third of the votes cast, and forming the official opposition in the legislature. The new legislature met for the first time on March 17, 1992.
