Marguerite Churchill (December 26, 1910[2][3] – January 9, 2000) was an American stage and film actress whose career lasted 30 years, from 1922 to 1952.

A child actress, Churchill made her first appearance on Broadway on Christmas Day 1922 (a date mistakenly described by some as her 13th birthday).

A Fox Film official saw her acting and gave her a contract which shortly afterwards led her to debut on screen in The Diplomats (1929).

She appeared with Wayne the following year in Girls Demand Excitement (1931), with Spencer Tracy and George Raft in Quick Millions (1931), with Will Rogers in Ambassador Bill (1931), with Warner Oland in Charlie Chan Carries On (1931), with her future husband George O'Brien in Riders of the Purple Sage (1931), with Charles Farrell in Girl Without a Room (1933), with Ralph Bellamy in The Final Hour (1936), with Boris Karloff in The Walking Dead (1936), and with Edward Van Sloan in Dracula's Daughter (1936).

On Broadway, Churchill performed in And Now Good-bye (1937), Dinner at Eight (1932), The Inside Story (1932), Skidding (1928), The Wild Man of Borneo (1927), House of Shadows (1927), and Why Not?
