Ridgewood Reservoir is a decommissioned 19th century reservoir that sits on the Brooklyn–Queens border within New York City and is part of Highland Park. The reservoir itself is actually on the Queens side of the border in the neighborhood of Glendale. The reservoir and park are bounded on the north by the Jackie Robinson Parkway, on the south by Highland Boulevard, on the west by the backyards of homes on Bulwer Place and on the east by Cypress Hills National Cemetery.
