Parkhouse Hill is a small but distinctive hill in the Peak District National Park in the English county of Derbyshire. It lies on the north side of the River Dove, close to the border with Staffordshire. Geologically, the hill is the remains of an atoll (a 'reef knoll') which is believed to have existed during the Carboniferous period when what is now the Peak District was covered by a tropical sea. Together with its higher but less distinctive neighbour, Chrome Hill, it forms the Chrome and Parkhouse Hills SSSI, cited for their geology and limestone flora.
