Sydney Lewis (October 24, 1919 – March 12, 1999) was a prominent Virginia businessman, philanthropist, and art collector.
Born in Richmond, Virginia, he was the founder of Best Products Co. (now defunct). He is the namesake of Lewis Hall at the Washington and Lee University School of Law, whose construction he and his wife, Frances, funded in 1976. Lewis himself held his B.A. from Washington and Lee (1940), and though he began the study of law, never received a law degree. He and his wife, Frances, were awarded the National Medal of Arts in 1987.
