Life with Father is a 1947 American Technicolor comedy film adapted from the 1939 play of the same name, which was inspired by the autobiography of stockbroker and The New Yorker essayist Clarence Day.

It tells the true story of Day and his family in the 1880s. His father, Clarence Sr., wants to be master of his house, but finds his wife, Vinnie, and his children ignoring him until they start making demands for him to change his life. The story draws largely on Clarence Sr.'s stubborn, sometimes ill-tempered nature and Vinnie's insistence that he be baptized. It stars William Powell and Irene Dunne as Clarence Sr. and his wife, supported by Elizabeth Taylor, Edmund Gwenn, ZaSu Pitts, Jimmy Lydon, and Martin Milner.
