The Howden Reservoir is a Y-shaped reservoir, top one of the three in the Upper Derwent Valley in Derbyshire, England. The longest arm is around 1.25 miles (2 km) in length. The reservoir is bounded at the southern end by Howden Dam; below this, the River Derwent flows immediately into Derwent Reservoir and subsequently the Ladybower Reservoir. Other tributaries include the River Westend, Howden Clough and Linch Clough.

Work commenced on the dams construction on the 16th July 1901 and completed July 1912. The works involved constructing a temporary village at Birchinlee, a temporary railway line from the main line at Bamford, construction of a link aqueduct to the Derwent Dam. The dam is of solid masonry construction, and convert|117|ft|m|abbr=on tall, 1080 ft long. and impounds 1.9 million gallons of water, from a catchment area of convert|5155|acre|km2.

To the east of the reservoir stands the hill of Featherbed Moss, one of the highest tops in the area at 545 m, and one of several tops of that name in the area.
