High Hazels Park is a large parkland area in Darnall, Sheffield, South Yorkshire, England. Since the 19th century Darnall has been a centre of coal and steel industry in Sheffield. High Hazels Park was built in 1850 by William Jeffcock (the first Mayor of Sheffield). 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. In 1895 the land was first used as a public recreation ground and was classed as one of the finest parks within the city of Sheffield.
