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

Nearby places are Lavendon and Turvey (over the bridge on the Bedfordshire side of the River Great Ouse).

Cold Brayfield is probably the place named as 'Bragenfelda' in a charter of 967.

[2] The elements of the name, 'brain' and 'field' are interpreted to mean 'open country on the crown of a hill'.

[3] The village name is later recorded in twelfth- and thirteenth-century charters as 'Brauefeld', 'Brawefeld' or 'Brauufeld',[4] and becomes 'Cold Brayfield' towards the end of the sixteenth century.
