The Duchy League was an English football competition based in the eastern half of Cornwall, but also included a few sides from over the border in Devon. The League was formed in 1965 as a merger of the Liskeard & District League and the St. Austell & District League. It had three divisions headed by the Duchy League Premier Division, which operated at level 13 of the English football league system. It was a feeder to the East Cornwall League. In 2014–15, Padstow United won the Premier Division, and earned promotion to the East Cornwall League.
