The Cape-class patrol boats were 95-foot (29 m) steel hull patrol boats with aluminum superstructures of the United States Coast Guard. They were unnamed until 1964, when they acquired names of U.S. capes of land. Originally designed for anti-submarine warfare (ASW), all 36 boats in this class were built at the United States Coast Guard Yard in Curtis Bay, Maryland.

The Cape class was originally developed as an ASW boat and as a replacement for the aging, World War II vintage, wooden 83-foot (25 m) patrol boats that were used mostly for search and rescue duties. With the outbreak of the Korean War and the requirement tasked to the Coast Guard to secure and patrol port facilities in the United States under the Magnuson Act of 1950, the complete replacement of the 83-foot boat was deferred and the 95-foot boat was used for harbor patrols. The first 95-foot hulls were laid down at the Coast Guard Yard in 1952 and were officially described as "seagoing patrol cutters". Because Coast Guard policy did not provide for naming cutters under 100 feet (30 m) at the time of their construction they were referred to by their hull number only and gained the Cape-class names in 1964 when the service changed the naming criteria to 65 feet (20 m). The class was named for North American geographic capes.

The Cape class was replaced by the 110-foot (34 m) Island class beginning in the late 1980s and many of the decommissioned cutters were transferred to nations of the Caribbean and South America by the Coast Guard.

There were three sub-classes or types that evolved as missions for the boat changed. The Type A was outfitted primarily for ASW. The Type B was fitted more for search and rescue (SAR) with the addition of scramble nets, a towing bit, and a large searchlight. The Type C vessels were constructed with a deck house aft of the bridge. Sixteen boats were overhauled as part of a renovation program began in the mid-late 1970s.
