The River Rivelin is a river in Sheffield, South Yorkshire, England.
It rises on the Hallam moors, in north west Sheffield, and joins the River Loxley (at Malin Bridge). The Rivelin Valley, through which the river flows, is a 3+1⁄2-mile-long woodland valley which includes the popular Rivelin Valley Nature Trail that was created in 1967. The valley has farmland on its gentler upper slopes. Tributaries include the Wyming Brook, Allen Sike and the Black Brook. The Rivelin Dams are to be found at the head of the valley.
A relatively fast-flowing river (it drops 80 metres between Rivelin Mill Bridge and Malin Bridge), the Rivelin is fed by a constant release of water from the nearby moorland peat. Its flow was exploited for centuries as a power source, driving the water wheels of up to twenty industries (forges, metal-working and flour mills) along its course.
