Eynesbury Hardwicke was an English civil parish which existed between 1895 and 2010; it was initially in the county of Huntingdonshire, and after 1974 it was in Cambridgeshire. The parish was created from the part of the ancient parish of Eynesbury which lay outside the urban district of St Neots. The old village of Eynesbury was within the urban district, and so Eynesbury Hardwicke covered the more rural parts of the old parish, including Caldecote Manor, Eynesbury Hardwick House, and the site of the deserted medieval village of Weald. The parish was abolished in 2010, when its area was split between the parishes of St Neots and Abbotsley.
