Oliver Smith (February 13, 1918 – January 23, 1994) was an American scenic designer.
Born in Waupun, Wisconsin, Smith attended Penn State, after which he moved to New York City and began to form friendships that blossomed into working relationships with such talents as Leonard Bernstein, Jerome Robbins, Carson McCullers, and Agnes de Mille. In his early 20s he lived at February House in Brooklyn with a coterie of famous people centered on George Davis and W. H. Auden. He tended the furnace, washed the dishes, and soothed the tempers of both residents and visitors. His career was launched with his designs for Léonide Massine's ballet Saratoga in 1941 and de Mille's Rodeo in 1942.
Smith designed dozens of Broadway musicals, films (Guys and Dolls, The Band Wagon, Oklahoma!, Porgy and Bess), and operas (La Traviata). His association with the American Ballet Theatre began in 1944, when he collaborated with Robbins and Bernstein on Fancy Free, which served as the inspiration for On the Town. The following year, he became Co-Director of ABT with Lucia Chase, a position he held until 1980. He designed the sets for ABT's complete 1967 production of Swan Lake, the first full-length version mounted by an American company.
