Robert Ainsworth (born 19 June 1952) is the British Member of Parliament for Coventry North East. He is a member of the Labour Party.

Known as Bob Ainsworth, he first became active as a trade unionist at the Jaguar plant in Coventry, and was convenor of the trade unions there. During 1982-83 he was a candidate member of the International Marxist Group, but he was never a full member of that organisation. He went on to become a member of Coventry City Council, and was deputy Labour group leader. He became MP for Coventry North East in 1992 after the sitting MP, John Hughes, was de-selected by the Constituency Labour Party. Since then he has been a junior minister at the Home Office, and a government whip.
