Wessenden Reservoir is the second in a series of four reservoirs in the Wessenden Valley above the village of Marsden in West Yorkshire, at the northern end of the Peak District National Park.

The reservoir was created by the construction of an earth embankment across Wessenden Brook.

The Wessenden Valley Woodland Project was initiated in 2017 to develop natural habitats with increased biodiversity.
