All About Lily Chou-Chou (リリイ・シュシュのすべて, Rirī Shushu no Subete) is a 2001 Japanese experimental coming-of-age film, written, directed, and edited by Shunji Iwai. The narrative follows several 14-year-old Japanese students, examining how enigmatic solo musician Lily Chou-Chou influences their lives.

The film is noted for an unconventional visual style which includes many jump cuts and shots with disjunctive contents, as well as for an elliptical narrative. These features, which have led the film to be described as restless or "explosive", are viewed by critics as efforts to artistically evoke the emotional lives of disaffected Japanese youth.

Critics mostly expressed positive views on All About Lily Chou-Chou. While some found the story's ambiguity frustrating, the film's lyricism drew praise.
