Charles Dukes, 1st Baron Dukeston (28 October 1881 – 14 May 1948) was a British trade unionist and Labour Party politician.
Born in Stourbridge, Dukes left school at the age of eleven, taking up work as an errand boy. When his family moved to Warrington, he joined working in a forge. He subsequently had a number of casual jobs throughout north west England, including working on the Manchester Ship Canal.
In 1909 his career as a trade union official began when he was elected secretary of the Warrington branch of the National Union of Gasworkers. He was a founding member of the British Socialist Party, and was elected to the party's national executive in 1914. During the First World War he was a conscientious objector, serving some time in prison. He became a district secretary in what had become the National Union of General Workers. From 1934 to 1946, Dukes was General Secretary of the National Union of General and Municipal Workers. From 1946 to 1947 he was President of the Trades Union Congress. In 1947 he was appointed a director of the Bank of England.
At the 1923 general election, Dukes was elected as the Member of Parliament (MP) for Warrington in Lancashire, narrowly defeating the sitting Conservative MP Alec Cunningham-Reid. When the First Labour Government fell in 1924, Dukes lost his seat in the resulting 1924 general election, unseated by his predecessor Cunningham-Reid.
