The Hogsmill River in Surrey and Greater London, England, is a small chalk stream tributary of the River Thames. It rises in Ewell and flows into the Thames at Kingston upon Thames on the lowest non-tidal reach, that above Teddington Lock.

The river is 10 km (6 mi) long and has a catchment area of about 73 km2 (28 sq mi).[1] Nearby land was formerly flood-meadows; following improvements it is now mostly sports grounds, a sewage treatment works and green space, save for Kingston and Epsom town centres. It is a habitat of many animals, fish and insects.

The 12th-century Clattern Bridge, one of the oldest road bridges in England, crosses the river in the southwest of Kingston town centre.[2] The Coronation Stone, now sited close to the river in Kingston, is believed to have been used for the coronation of Saxon kings in the 10th century. It was used as a horse mounting block until 1850 when it was mounted on a plinth in the town centre.

The river has five tributaries: Green Lanes Stream, Ewell Court Stream, Horton Stream, Bonesgate Stream and Tolworth Brook.
