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.

North East Somerset is a constituency represented in the House of Commons of the UK Parliament, since it was created for the 2010 general election, by Jacob Rees-Mogg of the Conservative Party.
