The River Kinder is a small river, only about 3 miles (4.8 km) long, in northwestern Derbyshire, England. Rising on the peat moorland plateau of Kinder Scout, it flows generally westwards to its confluence with the River Sett at Bowden Bridge. En route it flows through the Kinder Gates rocks, over the waterfall known as Kinder Downfall, and through Kinder Reservoir, built in 1903–12 by the Stockport Corporation Water Works. Until the 19th century at least, the name was formerly also applied to the River Sett as far as its confluence with the River Goyt in New Mills.

Kinder Scout is a moorland plateau and National Nature Reserve in the Dark Peak of the Derbyshire Peak District in England. Part of the moor, at 636 metres (2,087 ft) above sea level, is the highest point in the Peak District, in Derbyshire and the East Midlands.
