Long Crendon is a village and civil parish within Aylesbury Vale district in Buckinghamshire, England, about 3mi west of Haddenham and 2mi north-west of Thame in neighbouring Oxfordshire. The village has been called Long Crendon only since the English Civil War. The "Long" prefix refers to the length of the village at that time, and was added to differentiate it from nearby Grendon Underwood, which used to be known as "Crendon". This name is Old English and means 'Creoda's Hill' (in 1086 it was listed in the Domesday Book as Crededone).
