The More the Merrier is a 1943 American romantic comedy film produced and directed by George Stevens, and starring Jean Arthur, Joel McCrea, and Charles Coburn. The film's script—from Two's a Crowd, an original screenplay by Garson Kanin (uncredited)—was written by Robert Russell, Frank Ross, Richard Flournoy, and Lewis R. Foster. Set in Washington, D.C., the film presents a comic look at the housing shortage during World War II.

The film received six nominations at the 16th Academy Awards, among them Best Picture, Best Director for Stevens, Best Actress for Arthur, Best Writing (Original Motion Picture Story), and Best Writing (Screenplay). Coburn won Best Supporting Actor.

The film was remade in 1966 as Walk, Don't Run starring Cary Grant, Samantha Eggar, and Jim Hutton. The setting was changed to Tokyo, which had experienced housing shortages due to the 1964 Summer Olympics.
