They Met in the Dark is a 1943 British thriller film directed by Karel Lamac and starring James Mason, Joyce Howard and Edward Rigby. A cashiered Royal Naval officer and a young woman join forces to solve a murder and hunt down a German spy ring. The film features a single song sung by Phyllis Stanley, "Toddle Along" (Ben Frankel, Moira Heath).

Radio Times noted "an old-fashioned, run-of-the-mill and unlikely espionage thriller-cum-romance, it was topical during the Second World War years, but is rather unrewarding now" ; while Britmovie wrote, "there are capable performances from all involved but it’s Tom Walls, the urbane Aldwych farceur, who steals the limelight when cast against type as a charming villain."
