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.

The Somerset Levels are a coastal plain and wetland area of Somerset, England, running south from the Mendips to the Blackdown Hills.
