Voltaire is a 1933 American pre-Code biographical film directed by John G. Adolfi and starring George Arliss as Voltaire, an 18th-century French writer and philosopher.

George Arliss was an English actor, author, playwright, and filmmaker who found success in the United States. He was the first British actor to win an Academy Award – which he won for his performance as Victorian-era British prime minister Benjamin Disraeli in Disraeli (1929) – as well as the earliest-born actor of any category to win the honour. He specialized in successful biopics, such as Disraeli, Voltaire (1933), and Cardinal Richelieu (1935), as well as light comedies, which included The Millionaire (1931) and A Successful Calamity (1932).
