The Wyming Brook is a river in the City of Sheffield, England. Its source is the Redmires Reservoirs near the Hallam Moors. It flows in a northeasterly direction for over a kilometre down quite steep terrain into the lower of the Rivelin Dams. There is a path that runs alongside the brook which is popular with walkers. The path can be quite steep, with it and the brook falling over 100 m in a kilometre. The river flows almost its entire length within the Wyming Brook Nature Reserve.
