Lewis St. George Stubbs (June 14, 1878-May 12, 1958) was a prominent judge and politician in Manitoba, Canada. He served in the Legislative Assembly of Manitoba from 1936 to 1949 as an Independent, and was known for promoting left-wing and socially progressive causes. In 1908, he opened a legal practice in Birtle, where he also worked as a farmer. During the federal election of 1917, Stubbs was one of the few public figures in the community to oppose conscription and the government of Robert Borden.
