This article is the Electoral history of Lester B. Pearson, the fourteenth Prime Minister of Canada. A Liberal, he served one term as Prime Minister (1963–1968). He led the Liberal Party in four general elections, losing two (1958 and 1962) to John Diefenbaker, and winning two (1963 and 1965), defeating Diefenbaker both times.
