That Woman Opposite (U.S. City After Midnight) is a 1957 British crime drama, directed by Compton Bennett and starring Phyllis Kirk, Dan O'Herlihy and William Franklyn. The screenplay, also by Bennett, was adapted from John Dickson Carr's 1942 novel The Emperor's Snuff-Box.

The film was generally positively received by critics, with Picturegoer commenting: "At last, a British thriller with class...here's a gloss that usually comes with an import label". In a more measured but still approving critique, a Radio Times reviewer said: "Don't expect too much of this modest film...and you'll be agreeably entertained by an efficiently directed work graced by many recognisable faces".
