The River Seph (or River Sep) is a tributary of the River Rye (itself a tributary of the River Derwent) in North Yorkshire, England. The river flows for 13 miles (20.5 km) down Bilsdale and meets the Rye near the village of Hawnby. When the surrounding land was owned by Roger de Mowbray, the river was referred to as the Sep.
