Laleham Burway is a 1.6-square-kilometre (0.62 sq mi) tract of water-meadow and former water-meadow between the River Thames and Abbey River in the far north of Chertsey in Surrey. Its uses are varied. Part is Laleham Golf Club. Semi-permanent park homes in the west forms residential development along with a brief row of houses with gardens against the Thames. A reservoir and water works is on the island.

The Abbey River is a right-bank backwater of the River Thames in England, in Chertsey, Surrey — in the town's northern green and blue buffers. The L-shaped conduit adjoins mixed-use flood plain: water-meadows landscaped for a golf course, a motorway and a fresh water treatment works on the island it creates, Laleham Burway to its east and north in turn. Its offtake from the Thames is at the apex of Penton Hook, Staines upon Thames below its lower weir close to the Chertsey-Thorpe boundary in the Borough of Runnymede. Its outfall is the weir pool of Chertsey Lock back into the Thames, visible from Chertsey Bridge.
