Allington is a hamlet in north Wiltshire, England. It is on the edge of the market town of Chippenham, about 2 mi north-west of the town centre and about 0.3 mi north of the A420 road towards Bristol. Allington Bar is a farm and small hamlet on the A420. Allington Manor Farmhouse is from the mid 18th century and incorporates fragments of a 17th-century manor house; further fragments are within an 18th-century barn. Bolehyde Manor, a Grade II* listed 17th-century manor house and former home of Camilla Parker-Bowles, is a short distance north of Allington village. This Allington is not a former parish, but was a tithing of the parish of Chippenham. Since 1894 it has been in the civil parish of Chippenham Without. The settlement was designated as a conservation area in 1998, and in 2002 the area was extended to include the surrounding landscape.
