USS Kajeruna (SP-389) was a patrol vessel that served in the United States Navy from 1917 to 1919. The vessel had been built in 1902 as Hauoli for mining magnate Francis Marion "Borax" Smith but was replaced in 1903 by a second, larger vessel he named Hauoli. The first yacht was then named Seminole and for a time was returned to the builder, John N. Robins, and advertised for sale by the designer's firm. In 1911 Clinton W. Kinsella of New York purchased the yacht, apparently already renamed Kajeruna. After naval service the yacht was returned to the owner. On 31 March 1920 the ship was sold to British interests and renamed Tomas W. Beattie.
