The Portsmouth Naval Shipyard, often called the Portsmouth Navy Yard, is a United States Navy shipyard on Seavey's Island in Kittery, Maine, bordering Portsmouth, New Hampshire. The naval yard lies along the southern boundary of Maine on the Piscataqua River.

Founded on June 12, 1800, PNS is U.S. Navy's oldest continuously operating shipyard. Today, most of its work concerns the overhaul, repair, and modernization of submarines.[2]

As of November 2021, the shipyard employed more than 6,500 federal employees.[3] As well, some of the work is performed by private corporations (e.g., Delphinius Engineering of Eddystone, Pennsylvania; Oceaneering International of Chesapeake, Virginia; Orbis Sibro of Mount Pleasant, South Carolina; and Q.E.D. Systems Inc. of Virginia Beach, Virginia).[4]
