Bevin Boys were young British men conscripted to work in the coal mines of the United Kingdom, from December 1943 until 1948. Chosen at random from conscripts but also including volunteers, nearly 48,000 Bevin Boys performed vital but largely unrecognised service in the mines, many of them not released until years after the Second World War ended. Ten percent of those conscripted aged 18–25 were selected for this service.

The programme was named after Ernest Bevin, a former trade union official and then British Labour Party politician who was Minister of Labour and National Service in the wartime coalition government. At the beginning of the war the Government, underestimating the value of experienced coal-miners, conscripted them into the armed forces. By mid-1943 the coal mines had lost 36,000 workers, and these workers were generally not replaced due to the availability of cleaner work. It became evident that the miners needed to be replaced. The government made a plea to men liable to conscription to volunteer to work in the mines instead, but few offered and the shortage continued.
