Clumber Park is a country park in The Dukeries near Worksop in the civil parish of Clumber and Hardwick, Nottinghamshire, England. The estate, which was the seat of the Pelham-Clintons, Dukes of Newcastle, was purchased by the National Trust in 1946. It is listed Grade I on the Register of Historic Parks and Gardens. The main house was demolished in 1938 after damage by several fires. The nearby Grade I listed chapel in Gothic Revival style and a four-acre walled kitchen garden still survive.
