This is a list of United Kingdom Labour and Co-operative Party MPs. It includes all Members of Parliament (MPs) elected to the British House of Commons representing the Co-operative Party from 1918 to 1927, and Labour and Co-operative Party since 1927. Members of the Scottish Parliament or the Senedd are not listed.
Only official Labour and Co-operative MPs who have been formally endorsed by both parties are listed. Although many Labour MPs are also members of the Co-operative Party, they are only endorsed in elections by the Labour Party.
