Alan Aylesworth Macnaughton was a Canadian parliamentarian and Speaker of the Canadian House of Commons from 1963 to 1966. Macnaughton was born in Napanee, Ontario, and educated at Upper Canada College. He studied law at McGill University and began a law practice in Montreal where he served as a Crown Attorney from 1933 to 1942. Macnaughton first won a seat in the Canadian House of Commons in the 1949 election when he was returned as a Liberal Member of Parliament (MP) for the riding of Mount Royal. Macnaughton served as Chairman of the Public Accounts Committee after the 1958 election, and his performance in that position led to the newly-elected Liberal government nominating him for the position of Speaker following the 1963 election.
