Things Happen at Night is a 1947 British supernatural ghost comedy film directed by Francis Searle and starring Gordon Harker, Alfred Drayton, Robertson Hare and Garry Marsh. The film is based upon a stage play, The Poltergeist, by Frank Harvey. It was shot at Twickenham Studios. Despite the film's comparatively large budget it ended up being released as a second feature.

The film is set in an English country house which is haunted by a poltergeist. Besides damaging the house's contents, the poltergeist possesses a schoolgirl and causes her expulsion from school. The homeowners receive help from a ghost breaker.
