Charles Duncan (8 June 1865 – 6 July 1933) was a British Labour Party politician and trade unionist.

[4] Duncan joined Amalgamated Society of Engineers in 1888,[3] and was active in the trade union movement for the rest of his life.

[4] He earned the nickname 'Angel of Death' in World War I, because he toured the UK encouraging men to join the military; many of those would have died in the trenches.

[4][8] Duncan attempted unsuccessfully to re-enter the Commons when two by-elections were held in The Wrekin, Shropshire, in quick succession in February and November 1920.

[4] At the 1922 election, he stood in the Derbyshire mining constituency of Clay Cross, winning the seat by a large majority from a divided Liberal Party.
