USS Arval (SP-1045) was a United States Navy patrol vessel in commission from 1917 to 1919. Arval was built as a private motorboat of the same name in 1911 by the Stamford Motor Construction Company at Stamford, Connecticut. On 1 November 1917, the U.S. Navy acquired her from her owner, Donald N. Test, for use as a section patrol boat during World War I. She was commissioned the same day at Chicago, Illinois, as USS Arval (SP-1045) with Ensign Franklin Smith, USNRF, in command.
