Woman in a Dressing Gown is a 1957 British drama film directed by J. Lee Thompson and starring Yvonne Mitchell, Anthony Quayle, Sylvia Syms, and Carole Lesley.

The screenplay was written by Ted Willis, based on his 1956 ITV Television Playhouse play of the same name. The producer was Frank Godwin who called it "the first kitchen sink movie".

The film concerns a man who is having an extramarital affair and considers divorce, and his wife's reaction to the affair. Scenes compare and contrast the man's relationship with his wife versus his relationship with his lover. These are not only very different in content, but very different in film style, shots with his lover being in extreme close-up and/or unusually framed shots. Shots of the wife are mainly in wide angle, encompassing the chaotic mess of her house.

The film is considered an example of British social realism, and a prototypical version of Kitchen sink realism. Modern criticism has noted that it was more progressive in the field of gender politics than the British New Wave.
