Cheesequake State Park is a 1,610-acre (2.52 sq mi) state park located in Old Bridge, Middlesex County, New Jersey, in the United States. The New Jersey Legislature allocated $100,000 in 1937 to purchase property for the park. The state first acquired a 250-acre (100 ha) tract of farmland and a Civil War-era mansion from the Favier brothers in January 1938. Additional lands were acquired over the next two years, and the Civil Conservation Corps, part of the Works Progress Administration, helped develop the property. The park was opened in June 1940. It is operated and maintained by the New Jersey Division of Parks and Forestry and is part of the New Jersey Coastal Heritage Trail Route.
