Margery Hill // is a 546-metre (1,791 ft) hill on the Howden Moors in South Yorkshire, England. It lies towards the northern boundary of the Peak District National Park, between Langsett Reservoir to the northeast and Howden Reservoir to the southwest. The area is managed by the National Trust as part of their High Peak Estate.
The summit cairn has recently been shown to be a Bronze Age burial mound, after the peat in the area was dated at a uniform age of around 3,500 years, indicating a constructed rather than natural origin. The area has been designated a Scheduled Ancient Monument by English Heritage.
Margery Hill is the highest marked point within the boundaries of Sheffield. The land rises slightly to 548 metres (1,798 ft) about 1.5 kilometres (0.9 mi) to the south, near High Stones.
