The Piscataqua River (Abenaki language: Pskehtekwis) is a tidal river forming the boundary of the U.S. states of New Hampshire and Maine from its origin at the confluence of the Salmon Falls River and Cochecho River to the Atlantic Ocean. The drainage basin of the river is approximately , including the subwatersheds of the Great Works River and the five rivers flowing into Great Bay: the Bellamy River, Oyster, Lamprey River, Squamscott River, and Winnicut River.
The river runs southeastward, with New Hampshire to the south and west and Maine to the north and east, and empties into the Gulf of Maine east of Portsmouth, New Hampshire. The last before the sea are known as Portsmouth Harbor and have a tidal current of around . Beyond the tidal currents, the river has a flood current speed of 12 knots, making it the fastest river on the eastern seaboard of the United States and one of the fastest rivers in the country.

Once salmon, sturgeon, oysters, clams, scallops, lobsters, mussels, eels, seals, and many others species of marine life were common in the river, evidenced by such tributaries as the Salmon Falls River, Sturgeon Creek and Seal Rock in Eliot, Maine, the Oyster River in Durham, New Hampshire, and the Lamprey River in Newmarket, New Hampshire. All but the salmon and sturgeon remain abundant (although an increasing amount of verifiable sightings and encounters with Atlantic Salmon and Atlantic Sturgeon are being reported to New Hampshire Fish and Game), with fishing for striped bass and bluefish common recreational sports.
In the mid 1630s some of the region's earliest European settlers built a sawmill in what is today's Berwick, Maine, on a tributary above the head of tide of the Piscataqua.Palmer, Ansell W., ed.

After the Allies' European victory in the Second World War, four surrendered German traveled upriver to the Portsmouth Naval Shipyard, Nazi U-Boats Surrender at Portsmouth with their captains and crews interned as Max Hastings, Inferno, New York 2011, p. 630. at Portsmouth Naval Prison. U-805 was the first to arrive, towed up the river to a rendezvous with U.S. officials on a tugboat off the Navy Yard on May 15, 1945. U-873 and U-1228 arrived the next day.
U-234, by far the greatest prize, arrived on May 19, seized off Nova Scotia by the U.S. destroyer escort . It had left Germany with a cargo bound for Japan of a disassembled Messerschmitt Me 262 jet plane, the most sophisticated fighter of World War II; two top Japanese scientists; and two high-ranking Nazi officers. While this was enough to create a media sensation, it was decades later before the U.S. government revealed that the sub also carried a top secret load of uranium oxide produced by the German atomic weapons program bound for a last-ditch Japanese effort. Instead, the extremely valuable nuclear material was diverted to the U.S.' top secret Manhattan Project, and ended up part of the bomb the U.S. Army Air Corps dropped over Hiroshima to hasten the end of the Pacific war.
The shipyard is located on Seavey's Island in Kittery, Maine near the Piscataqua's mouth. Long regarded by some as being in New Hampshire, the yard was claimed by that state into the 2000s. However, the Piscataqua River border dispute over Seavey's Island was settled by a 2001 U.S. Supreme Court decision which cited a 1977 decision affirming New Hampshire's claim that the state borders met at the center of the river's navigable channel as described in a 1740 decree, thus placing the island in Maine.
Estuary
The Piscataqua River and its tributaries, including Great Bay, form a substantial estuary. Two rivers, the Salmon Falls and Cocheco River, join to form the Piscataqua on the eastern edge of Dover, New Hampshire, at the northwest corner of Eliot, Maine. Five rivers with tidal stretches flow into Great Bay: the Bellamy River, Oyster, Lamprey River, Squamscott River, and Winnicut River, and the Great Works River drains into the tidal portion of the Salmon Falls.
