Robert Cruise (11 December 1868 – 19 June 1932) was a Canadian Member of Parliament for Dauphin, Manitoba.
Born in Lachute, Quebec, the son of Peter and Margaret (Mill) Cruise, he was a farmer in Quebec until 1893 when he moved to Manitoba settling in Dauphin where he acquired a farm of 160 acres (0.65 km2).
Cruise was elected as a Liberal in the 1911 federal election, however, as a result of the Conscription Crisis of 1917 he and many other English-Canadian Liberals crossed the floor to support the Union government formed by Robert Borden in 1917.
Cruise stood for re-election in the 1917 election and was acclaimed as a Government supporter.
Cruise was soundly defeated by William John Ward, a candidate for the new Progressive Party of Canada.
