The River Lambourn is a chalk stream in the English county of Berkshire. It rises in the Berkshire Downs near its namesake village of Lambourn and is a tributary of the River Kennet, which is itself a tributary of the River Thames.
The upper reaches of the river are seasonal, with a perennial source derived from a number of springs located upstream of the village of Great Shefford. At times when the water table in the chalk aquifer feeding the river is high (usually between November and March) the source of the river migrates upstream. Along the bourn section of the river are located the villages of Eastbury and East Garston, while along the perennial section of the river are the villages of Great Shefford, Welford, Boxford, Bagnor, Donnington and Shaw. Below Shaw is the confluence of the River Lambourn with the River Kennet, located between Newbury and Thatcham. The River Lambourn itself has a single perennial tributary, the Winterbourne Stream, which joins it at the village of Bagnor.
The Lambourn Valley Way from the Uffington White Horse to Newbury generally follows the River Lambourn from Lambourn to Donnington Castle, in many places using the embankments of the old Lambourn Valley Railway.
