The 1959 Manitoba general election was held on May 14, 1959 to elect 57 members to the Legislative Assembly of Manitoba, Canada. It resulted in a majority victory for the incumbent Progressive Conservatives under the leadership of Premier Dufferin Roblin. It was the first time since the 1914 election that the PCs won an outright majority in the province, when they were led by Dufferin Roblin's grandfather, Sir Rodmond Roblin.
Roblin's PCs won 36 seats against 11 for the Liberal-Progressives, led by former Premier Douglas Campbell, and 10 for the social democratic Co-operative Commonwealth Federation led by Lloyd Stinson. The PCs took 25 percent more votes than it had received in the previous election just one year before but took 40 percent more seats than it had won in 1958. They had won 117,822 votes in 1958, compared to 147,000 in 1959.
The Manitoba Social Credit Party, which won 2 seats in the 1958 election, did not contest any seats during the election and regained a foothold in the legislature only during a subsequent by-election. The communist Labor-Progressive Party contested three ridings but did not win any.
The election is the last one to be fought by candidates with the "Liberal-Progressive," "Co-operative Commonwealth," or "Labor-Progressive" labels in Manitoba. The Liberal-Progressives dropped the latter half in 1961 and ran all subsequent elections as "Liberals." Similarly, the Labor-Progressive candidates returned to the "Communist" label. The CCF changed its name following the national party's re-incorporation into the New Democratic Party and ran all future elections as Manitoba New Democrats.
