Vivian Augustus Marshall (later Fries and Millett, March 18, 1888 – May 18, 1969) was an American diver, vaudeville performer and film actress.

Born in California, Marshall's family moved to Oregon during her youth and she gained notoriety for her aquatic skills while a member of the Multnomah Athletic Club in Portland and later performed public stunt dives from heights of 70 feet and above.

[3] In 1906, Vivian Marshall first gained local attention for swimming from the docks at Captain Bundy's Bath House in Oregon City to the west side of the Willamette River and back without resting.

[8][15] In February 1913, Marshall performed a publicity stunt in which she dove 75 feet from the 11th Street Bridge in Tacoma, Washington into the icy City Waterway below and swam 100 yards to a boat launch.

[19] Marshall's first international vaudeville performance came in April 1913 aboard the steamer SS Mount McKinley, which was docked off the Coronado Islands in Mexico.

The film, entitled He Got Himself a Wife, was produced by Vitagraph Studios and due to an error in post-production her credit was omitted despite being prominently featured.

The studio sent out corrections to certain publications like The Moving Picture World and the Los Angeles Herald and asked them to credit Marshall when they wrote about the film.
