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 (published in 1943). The screenplay is 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). They hope to arrange her marriage to a peer, thereby repairing their fortunes and their social status.
