Dead of Night is a 1945 black and white British anthology supernatural horror film, made by Ealing Studios. The individual segments were directed by Alberto Cavalcanti, Charles Crichton, Basil Dearden and Robert Hamer. It stars Mervyn Johns, Googie Withers, Sally Ann Howes and Michael Redgrave. The film is best remembered for the concluding story featuring Redgrave and an insane ventriloquist's malevolent dummy.

Dead of Night is a rare British horror film of the 1940s; horror films were banned from production in Britain during World War II. It had an influence on subsequent British films in the genre. Both of John Baines' stories were reused for later films and the ventriloquist dummy episode was adapted into the pilot episode of the long-running CBS radio series Escape.

While primarily in the horror genre, the film has shades of the comedy that would make the studio's name.
