Levi Addison Ault (November 1851 – February 1930) was a Canadian-born American businessman and bureaucrat whose career was closely associated with the city of Cincinnati, Ohio, where he earned the nickname "Father of Cincinnati's parks".
Born in Mille Roches, Province of Canada to a successful fabric manufacturer, Ault moved to Wisconsin in his teens, where he worked as a bookkeeper.
Two years later, Ault and his business partner Frank Wiborg incorporated Ault & Wiborg, an ink manufacturer that became the world's top producer and supplier of inks and lithograph supplies.
He served as chair of the board from 1908 to 1926, and donated 204 acres (825,000 m2) of land to the city to create Ault Park.
