The 2003 Manitoba general election was held on June 3, 2003 to elect Members of the Legislative Assembly of the Province of Manitoba, Canada. It was won by the New Democratic Party, which won 35 seats out of 57 (net gain of 3), securing another term for premier Gary Doer.
The Progressive Conservative Party finished second with twenty seats, a net loss of 4 from 1999. The Liberal Party won two seats, a net gain of one from the previous election. 
An article in "The Globe and Mail" attributed the NDP's strong performance to premier Doer's tenure, where he was seen as having "delivered a reasonable economic performance and a steady stream of budget surpluses."
