Remember Last Night? is a 1935 American mystery comedy film directed by James Whale. The film, based on the novel The Hangover Murders, is about the investigation of the murder of one of a group of friends. The survivors are unable to recall the events of the night of the murder because they were all too drunk. Remember Last Night? features an ensemble cast headed by Edward Arnold, Constance Cummings, and Robert Young.

Whale convinced Universal Studios head Carl Laemmle, Jr. to buy the screen rights to the novel so Whale could avoid directing Dracula's Daughter, as he wished not to direct another horror film so soon after shooting Bride of Frankenstein. Initial drafts of the screenplay were deemed unsuitable under the Production Code because of the focus on excessive drinking. The novel's original title was also unsuitable because of the word "hangover". Following revisions, the film was approved and was released on November 4, 1935 to mixed reviews and poor box office results.
