Alice's Birthday is a 2009 Russian traditionally animated children's science fiction film, directed by Sergey Seryogin and produced by Master-film studio. The film is based on a novella of the same name by Kir Bulychov about Alisa (Alice) Selezneva, a teenage girl from the future. It is a spiritual successor to 1981 animated film The Mystery of the Third Planet, from which it draws a heavy influence.

Kir Bulychev was a pen name of Igor Vsevolodovich Mozheiko, a Soviet Russian science fiction writer, critic, translator and historian. His magnum opus is a children's science fiction series Alisa Selezneva, although most of his books are adult-oriented. His books were adapted for film, TV, and animation over 20 times – more than any other Russian science fiction author – and Bulychev himself wrote scripts for early adaptations.
