USS East Hampton (SP-573) was a United States Navy minesweeper, patrol vessel, and lightvessel in commission from 1917 to 1919.

East Hampton was built as a commercial steam trawler of the same name by Cobb and Butler at Rockland, Maine, in 1913.

On 18 April 1917, the U.S. Navy purchased her from the Trident Fisheries Company of Portland, Maine, as a section patrol vessel and minesweeper during World War I.

Assigned to the 1st Naval District in northern New England, East Hampton served on patrol, minesweeping, towing, and icebreaking duties.

Between June and August 1918, she temporarily left those duties to escort U.S. Navy submarine chasers on voyages to Bermuda and the Azores, after which she resumed her operations in the 1st Naval District for the rest of World War I.
