High Hazels Park is a 20-hectare parkland area in Darnall, Sheffield, South Yorkshire, England. Since the 19th century, Darnall has been a centre of the coal and steel industry in Sheffield. High Hazels House, located in the park, was built in 1850 by William Jeffcock. In 1894, Sheffield City Council (the Corporation of Sheffield) bought the land and house from the Duke of Norfolk and Messers Jeffcock for £10,875.
