Marguerite Churchill (December 26, 1910 – January 9, 2000) was an American film actress with a film career spanning from 1929 to 1952. She is best known today as John Wayne's first leading lady, in The Big Trail (1930).

She was the daughter of a producer who owned a chain of theaters, but he died when she was ten years old. She was educated in New York City at the Professional Children's School and the Theatre Guild Dramatic School. She appeared on stage and was applauded on Broadway as a leading lady when just sixteen years old. An official of the Fox Company saw her acting and gave her a contract which shortly afterwards led her to debut on screen in The Diplomats.
