The Mansfield by-election, 1941 was a parliamentary by-election held for the British House of Commons constituency of Mansfield on 9 April 1941. The seat had become vacant when the Labour Member of Parliament Charles Brown had died on 22 December 1940. Brown had held the seat since the 1929 general election. The Labour party selected as its candidate Bernard Taylor, who had been Brown's election agent since 1929. The parties in the war-time Coalition Government had agreed not to contest vacancies in seats held by other coalition parties, so Taylor was returned unopposed.
