Peasedown St John is a village and civil parish in Somerset, England, standing on a hilltop roughly 5 miles (8 km) south-southwest of the city of Bath, and 2 miles (3 km) north-east of the town of Radstock at the foot of the Mendip Hills. Peasedown used to be a coal mining village, and after the last of the mines shut in the 1970s it became a dormitory village for Bath, Trowbridge and to a lesser extent Bristol. Its size was increased by substantial housing developments in the 1960s, 1970s and late 1990s, making it one of the largest villages in Somerset.

The Somerset Coalfield in northern Somerset, England is an area where coal was mined from the 15th century until 1973. It is part of a larger coalfield which stretched into southern Gloucestershire. The Somerset coalfield stretched from Cromhall in the north to the Mendip Hills in the south, and from Bath in the east to Nailsea in the west, a total area of about 240 square miles (622 km2). Most of the pits on the coalfield were concentrated in the Cam Brook, Wellow Brook and Nettlebridge Valleys and around Radstock and Farrington Gurney. The pits were grouped geographically, with clusters of pits close together working the same coal seams often under the same ownership. Many pits shared the trackways and tramways which connected them to the Somerset Coal Canal or railways for distribution.
