Brent Knoll is a 137-metre-high (449 ft) hill on the Somerset Levels, in Somerset, England. It is located roughly halfway between Weston-super-Mare and Bridgwater, 2.5 miles (4.0 km) from the Bristol Channel coast at Burnham-on-Sea. At the foot of the hill are two villages East Brent and Brent Knoll, which takes its name from the hill but was previously called South Brent. The hill's size and isolated position on the levels mean that it dominates the landscape and can be seen for many miles, and its prominence is emphasised to travellers because the Bristol to Taunton railway line, M5 motorway, A370 and A38 roads all pass within a mile or less from its base.

Somerset is a rural county in the southwest of England, covering 4,171 square kilometres (1,610 sq mi). It is bounded on the north-west by the Bristol Channel, on the north by Bristol and Gloucestershire, on the north-east by Wiltshire, on the south-east by Dorset, and on the south west and west by Devon. It has broad central plains with several ranges of low hills. The landscape divides into four main geological sections from the Silurian through the Devonian and Carboniferous to the Permian which influence the landscape, together with water-related features.
