The Socialist Campaign Group, officially the Socialist Campaign Group of Labour MPs and also known as the Campaign Group, is a left-wing, democratic socialist grouping of the Labour Party's Members of Parliament in the House of Commons of the United Kingdom. It was formed in December 1982 following the 1981 Labour Party deputy leadership election when a number of soft left MPs, led by Neil Kinnock, refused to back Tony Benn's campaign, leading a number of left-wing Benn-supporting MPs to split from the Tribune Group to form the Socialist Campaign Group.
