Louis Ralph (Bud) Sherman (December 24, 1926 – January 9, 2015) was a politician in Manitoba, Canada. He served in the House of Commons of Canada during the 1960s, and was a Progressive Conservative member of the Legislative Assembly of Manitoba from 1969 to 1984, serving as a cabinet minister in the government of Sterling Lyon.
The son of Louis Ralph Sherman, Archbishop of Rupert's Land, and Caroline Zerelda Gillmor, Sherman was born in Quebec City, Quebec. He was educated at the University of Manitoba. He served with the Canadian Officers' Training Corps in 1947-49, graduating as a First Lieutenant. Subsequently, he worked as a broadcaster, journalist, and newspaper editor. In 1955, Sherman married Elizabeth Ann Beaton.
In the Canadian federal election of 1965, Sherman was elected to the House of Commons for the riding of Winnipeg South as a Progressive Conservative, defeating Liberal Margaret Konantz by about 3,000 votes (Sidney Green of the New Democratic Party was third). Sherman served as an opposition MP for three years, before losing his seat to high-profile Liberal candidate James Richardson by over 8,000 votes in the federal election of 1968. Following his loss, he wrote a regular column in the Winnipeg Tribune.
