Cannock Chase Coalfield is a coalfield in Staffordshire, England, lying directly under Cannock Chase. It forms a rough triangle between Brereton, Essington and Pelsall.
The Cannock Chase Coalfield lies just to the north of the South Staffordshire Coalfield, from which it is separated by the Bentley Fault. The seams under Cannock Chase are much deeper than those in South Staffordshire, being around 1,600 feet (490 m) near Rugeley, compared to around 800 feet (240 m) in South Staffordshire.
By 1890, the coalfield was producing 3 million tons of coal per year, and by 1933 this had risen to over 5 million tons.
The last working coal mine beneath Cannock Chase, Littleton Colliery, was situated two miles north of Cannock in the village of Huntington on the A34 and closed on 3 December 1993. Some of the coal from the mine was taken to power the nearby Rugeley Power Station.
