Moulsoe is a village and civil parish in the unitary authority area of the City of Milton Keynes, Buckinghamshire, England.

The village name is an Old English language word which means 'Mul's hill spur'.

[4] As of 2019[update], the parish is mainly rural but a large area just west of the village has been identified for future expansion of Milton Keynes.

Other buildings are of brick apart from some concrete council houses to the west and the church which is of stone, and dates from the 12th century.

[7] Caldecote is a tiny hamlet in the parish, notable because of it being mentioned in Domesday.
