The Heritage-class cutter, also known as the Offshore Patrol Cutter and the Maritime Security Cutter, Medium, is a cutter class of the United States Coast Guard (USCG), developed as part of the Integrated Deepwater System Program and built by Eastern Shipbuilding and Austal USA. Construction of the first vessel in the class began in January 2019. As they are completed, it is expected that they will replace 270-foot (82 m) Famous- and 210-foot (64 m) Reliance-class Medium Endurance Cutters.

On June 7, 2025 a temporary stop-work order was issued on the third and fourth hulls of the class, both at Eastern Shipbuilding. The order did not effect hulls planned at Austal USA.
