Mrs. Miniver is a 1942 American romantic war drama film directed by William Wyler, and starring Greer Garson and Walter Pidgeon. Inspired by the 1940 novel Mrs. Miniver by Jan Struther, it shows how the life of an unassuming British housewife in rural England is affected by World War II. Produced and distributed by Metro-Goldwyn-Mayer, its supporting cast includes Teresa Wright, May Whitty, Reginald Owen, Henry Travers, Richard Ney and Henry Wilcoxon.

It was a critical and a commercial success, becoming the highest-grossing film of 1942 and winning six Academy Awards, including Best Picture, Best Director, Best Actress (Garson), and Best Supporting Actress (Teresa Wright). It was the first film centered on World War II to win Best Picture, and the first to receive five acting nominations. The film ranked 40th on the American Film Institute's list of most inspirational movies.

In 2009, the film was selected for preservation in the United States National Film Registry by the Library of Congress as "culturally, historically, or aesthetically significant".

A sequel, The Miniver Story (1950) was made with Greer Garson and Walter Pidgeon reprising their roles.
