USS Lowell (SP-504) was a United States Navy patrol vessel and minesweeper in commission from 1917 to 1919.

Lowell was built as a commercial steam lighter of the same name in 1909 by Verdin's Yard at Staten Island, New York.

The U.S. Navy acquired Lowell under charter from her owner, Neptune Line, Inc., of New York City, on 29 September 1917 for World War I service as a patrol vessel and minesweeper.

The Navy took control of her and commissioned her the same day at Tompkinsville on Staten Island as USS Lowell (SP-504).

In addition, she operated as a minesweeper and swept for naval mines in The Narrows and off southern Long Island.
