The United States **N class submarines** were a class of seven coastal defense submarines of the United States Navy.

The boats were constructed by two companies to slightly different specifications; *N-1*, *N-2*, and *N-3* by the Seattle Construction and Drydock Company of Seattle, Washington, and *N-4*, *N-5*, *N-6*, and *N-7* by the Lake Torpedo Boat Company of Bridgeport, Connecticut. The N-boats built by Lake are sometimes considered a separate class.

Commissioned during World War I, they were assigned to the 1st Naval District and patrolled the New England coast.

By 1922 the Seattle boats were assigned to the Submarine School, New London, while the Lake boats were all scrapped in that year.
