Cannock, population 29,018 at the 2011 census, is the most populous of three towns in the district of Cannock Chase in the central southern part of the county of Staffordshire in the West Midlands region of England.
Cannock lies to the north of the West Midlands conurbation on the M6, A34 and A5 roads, and to the south of Cannock Chase, an Area of Outstanding Natural Beauty (AONB). Cannock is served by a railway station on the Chase Line. The town comprises four district council electoral wards and the Cannock South ward includes the civil parish of Bridgtown, but the rest of Cannock is unparished.
Cannock was called Chenet in the Domesday Book of 1086. It was called Chnoc c.1130, Cnot in 1156, Canot in 1157, and Canoc in 1198. Cannock is probably Old English cnocc meaning 'hillock', modified by Norman pronunciation by the insertion of a vowel to Canoc. The name may refer to Shoal Hill, north-west of the town.
Cannock was a small rural community until mining increased heavily during the mid-to-late 19th century. The area then continued to grow rapidly with many industries coming to the area because of its proximity to the Black Country and its coal reserves. Cannock's population continued to increase steadily in the 20th century and its slight fall since the 1981 census has been more than compensated for by house-building in the adjoining village of Heath Hayes. The last colliery to close in the town was Mid Cannock in 1967, and the last remaining colliery to close in the Cannock Chase area was Littleton (in Huntington) in 1993. There is now no heavy industry in the area, and Cannock is home to many commuters working in the surrounding towns and cities.
