The 1903 Manitoba general election was held on July 20, 1903, to elect members of the Legislative Assembly of the Province of Manitoba, Canada. The result was a second consecutive majority government for the Conservative Party of Manitoba, now led by Premier Rodmond Roblin. Roblin's electoral machine won a landslide thirty-two seats, while the opposition Manitoba Liberal Party under former premier Thomas Greenway won only eight. The Winnipeg Labour Party also contested two constituencies, winning none.
