The River Eden in West Kent is a tributary of the River Medway. It travels through the Weald of Kent from the border with Surrey, rising from the source in Titsey parish, Surrey, about 350 metres north of Clacket Lane motorway services, and flowing eastward through the Wealden clay to join the River Medway near Penshurst, Kent.

The section from its source to where the Gibbs Brook joins it is also known as the Broadmead Water.Its name is a back formation deriving from Edenbridge, the main town through which it flows, and which was originally called in the Old English language “Eadhelmsbrigge” (“Eadhelm’s Bridge”).
