Angel's Egg (Japanese: 天使のたまご, Hepburn: Tenshi no Tamago) is a Japanese art film original video animation (OVA) written and directed by Mamoru Oshii. Released by Tokuma Shoten on 15 December 1985, the film was a collaboration between artist Yoshitaka Amano and Oshii. The film stars two nameless characters, a young girl who protects an egg, who bonds with a boy who has a dream about a bird. It was the first original project by Oshii and carries themes found in his other works.

It features very little spoken dialogue and a story that is strongly allegorical which has led to many viewers being confused about the film's supposed meaning. The film uses Biblical allusions and has been described as a cult classic.
