The Upper Derwent Valley is an area of the Peak District National Park in England. It largely lies in Derbyshire, but its north eastern area lies in Sheffield, South Yorkshire. Its most significant features are the Derwent Dams, Ladybower, Derwent and Howden, which form Ladybower Reservoir, Derwent Reservoir and Howden Reservoir respectively.

The Peak District is an upland area in England, at the southern end of the Pennines. Mostly in Derbyshire, it extends into Cheshire, Greater Manchester, Staffordshire, West Yorkshire and South Yorkshire. It is subdivided into the Dark Peak, moorland dominated by gritstone, and the White Peak, a limestone area with valleys and gorges. The Dark Peak forms an arc on the north, east and west of the district, and the White Peak covers central and southern areas. The highest point is Kinder Scout. Most of the area is within the Peak District National Park, a protected landscape designated in 1951.
