West Rock Ridge State Park is a public recreation area located in New Haven, Hamden, and Woodbridge, Connecticut.

The park's 7 miles (11 km) of open west-facing cliffs offer vistas encompassing Metropolitan New Haven and suburban towns to the west.

In the 17th century, West Rock served as the hideout for Edward Whalley and his son-in-law, Gen. William Goffe, two of the three "regicide judges" whom New Haven honors by streets bearing their surnames (41°18′47″N 72°55′59″W / 41.313094°N 72.932920°W / 41.313094; -72.932920 (intersection)).

[4] An act in 2003 gave right of first refusal to the Department of Environmental Protection to purchase private land for sale within the West Rock Ridge conservation area, with the object of increasing the size of the park.

Other park recreational uses include hiking, bicycling, fishing, car-top boating, horseback riding, picnicking, cross-country skiing, and rock climbing.
