Paul Muni (born Meshilem Meier Weisenfreund; 22 September 1895 – 25 August 1967) was an Austrian-born American stage and film actor. During the 1930s, he was considered one of the most prestigious actors at Warner Brothers studios, and one of the rare actors who was given the privilege of choosing which parts he wanted.

His acting quality, usually playing a powerful character, such as the lead in Scarface (1932), was partly a result of his intense preparation for his parts, often immersing himself in study of the real character's traits and mannerisms. He was also highly skilled in using make-up techniques, a talent he learned from his parents, who were also actors, and from his early years on stage with the Yiddish Theater, in New York. At the age of 12, he played the stage role of an 80-year-old man; in one of his films, Seven Faces, he played seven different characters.

He was nominated six times for an Oscar, winning once as Best Actor in The Story of Louis Pasteur.
