The Night of January 16th is a 1941 American crime drama film directed by William Clemens, based on a 1934 play of the same name by Ayn Rand. The story follows Steve Van Ruyle and Kit Lane as they investigate the apparent murder of Lane's boss, in an attempt to clear her as a suspect.

Night of January 16th is a theatrical play by Russian-American author Ayn Rand, inspired by the death of the "Match King", Ivar Kreuger. Set in a courtroom during a murder trial, an unusual feature of the play is that members of the audience are chosen to play the jury. The court hears the case of Karen Andre, a former secretary and lover of businessman Bjorn Faulkner, of whose murder she is accused. The play does not directly portray the events leading to Faulkner's death; instead the jury must rely on character testimony to decide whether Andre is guilty. The play's ending depends on the verdict. Rand's intention was to dramatize a conflict between individualism and conformity, with the jury's verdict revealing which viewpoint they preferred.
