Thorncroft Manor is an eighteenth-century manor in Leatherhead, Surrey. It is one of two feudal manors dating to Norman times, and was rebuilt in the 1770s in the Adamesque style. Notable figures who lived at the manor include Sir Thomas Bloodworth (1620–1682), who was the Lord Mayor of London during the Great Fire of London in 1666, and Colonel John Drinkwater Bethune (1762–1844), an army officer and military historian, who lived at the manor for the last six years of his life and is buried in the parish churchyard.
