USS Spray (ID-2491) was a United States Navy trawler which served as a minesweeper and was in commission from 1918 to 1919.

Spray was built as a civilian fishing trawler in 1905 by the Fore River Shipbuilding Company at Quincy, Massachusetts.

In 1917, the Russian Empire purchased Spray and the trawlers Foam and Ripple from the Bay State Fishing Company of Boston, Massachusetts, intending to place them in Imperial Russian Navy service during World War I, but the outbreak of the Russian Revolution that year prevented the three ships from leaving the United States.

On 29 May 1918, the U.S. Navy chartered all three ships from the Russian Government for World War I use.

2491, placed under the control of the Commandant, 3rd Naval District, and commissioned on 1 June 1918 as USS Spray (ID-2491).
