Waltz with Bashir (Hebrew: ואלס עם באשיר, translit. Vals Im Bashir) is a 2008 adult animated war documentary film written, produced, and directed by Ari Folman. It depicts Folman's search for lost memories of his experience as a soldier during the 1982 Lebanon War and the Sabra and Shatila massacre. It was the first Israeli feature-length animated film released theatrically since Joseph the Dreamer in 1962.

The film premiered at the 2008 Cannes Film Festival, where it competed for the Palme d'Or. Subsequently, it received wide acclaim from critics and audiences alike, with particular praise given to its themes, animation, direction, story, Max Richter's score, and Nili Feller's editing, although it drew controversies in some Arab countries. It is considered a groundbreaking achievement for adult animated films, particularly its use of visualized rotoscoping animation in documentary and personal reflection that explores the psychological and physical damage of war, setting it apart from most raunchy-like animated films by tackling realistic and complex, mature themes not typically seen in mainstream animation.

Waltz with Bashir garnered numerous accolades for the first time in an R-rated and non-English-language animated film including the Golden Globe Award for Best Foreign Language Film, the Critics' Choice Movie Award for Best Foreign Language Film, the National Society of Film Critics Award for Best Film, WGA's Best Documentary Screenplay and DGA's Outstanding Directorial Achievement in Documentary, and the International Documentary Association Award for Best Feature Documentary, and a nomination of Academy Award for Best Foreign Language Film.
