The 1973 Manitoba general election was held on June 28, 1973 to elect Members of the Legislative Assembly of the Province of Manitoba, Canada. It was won by the social-democratic New Democratic Party, which took 31 of 57 seats to win government in its own right for the first time. The Progressive Conservative Party finished second with 21, while the Manitoba Liberal Party took the remaining five. The Manitoba Social Credit Party lost its only seat.
A right-of-centre municipal organization known as the Independent Citizens' Election Committee convinced the Progressive Conservative and Liberal parties to avoid competing against each other in certain Winnipeg-area ridings, such that a single "anti-socialist" alternative to the NDP could be offered. This campaign was generally unsuccessful.
