Kitty is a 1945 film, a costume drama set in London during the 1780s, directed by Mitchell Leisen, based on the novel of the same name by Rosamond Marshall, with a screenplay by Karl Tunberg. It stars Paulette Goddard, Ray Milland, Constance Collier, Patric Knowles, Reginald Owen, and Cecil Kellaway as the English painter Thomas Gainsborough. In a broad interpretation of George Bernard Shaw's Pygmalion, the film tells the rags-to-riches story of a beautiful young cockney guttersnipe who is given a complete makeover by an impoverished aristocrat (Milland) and his aunt (Collier) in hopes of arranging her marriage to a peer, thereby repairing their fortunes and their social status.

James Mitchell Leisen was an American director, art director, and costume designer.
