The River Wandle is a right-bank tributary of the River Thames in south London, England. With a total length of about 9 miles (14 km), the river passes through the London boroughs of Croydon, Sutton, Merton and Wandsworth, where it reaches the Thames. A short headwater – the Caterham Bourne – is partially in Surrey, the historic county of the river's catchment. Tributaries of the Wandle include Carshalton Ponds and Norbury Brook.

The Wandle Trail follows the course of the river from Croydon to Wandsworth.
