The Greenock by-election, 1955 was a parliamentary by-election held on 8 December 1955 for the British House of Commons constituency of Greenock in Renfrewshire, Scotland.

The vacancy had been created by the death of the incumbent Labour MP Hector McNeil, and the seat was won by the future Labour Minister Dickson Mabon.

Labour selected Mabon, who at only thirty would become the youngest Labour MP. He had served as a Bevin Boy and in the army. He had been chairman of the Labour Club (1948–50), then chairman of the National Association of Labour Students in 1949–1950, and finally president of Glasgow University Union in 1951–52, and of the Scottish Union of Students, 1954–55.
