Ravensdale Park is a civil parish in the Derbyshire Dales district of Derbyshire roughly 3 mi WSW of Belper, Derbyshire, England, midway between Turnditch and Brailsford. The population of the civil parish as taken at the 2011 Census was less than 100. Details are included in the South Derbyshire civil parish of Dalbury Lees. It originated as one of the seven royal parks within Duffield Frith.

Parts of the former deer park are designated as a scheduled monument.
