USS Joyance (SP-72) was an armed yacht that served in the United States Navy as a patrol vessel from 1917 to 1919. Joyance was built as the private steam yacht Cavalier in 1907 by Robert Jacobs at City Island, New York. By the time the U.S. Navy inspected her for possible World War I service—describing her as being of "light construction"—she had been renamed Joyance. The Navy acquired her in May 1917 and commissioned her on 20 July 1917 as USS Joyance (SP-72) with Boatswain Martin Grady, USNRF, in command.
