Once part of the Brookhaven National Laboratory, the Brookhaven State Park is a state recreational area and native vegetation preserve in Ridge, New York.

Other than being part of the Brookhaven National Laboratory, the current Brookhaven State Park was also the site of a military installation called Camp Upton. The park covers over 1,638 acres of forested land and is considered an important part in the central core of the Long Island Pine Barrens. The park itself sits alongside the William Floyd Parkway and is easy to locate and enter. Interested hikers may want to explore the Brookhaven trails that goes through the park and links with the Paumanok path.

Other than the oak forest, the park also contains some scattered wetlands.
