Avalon (Japanese: アヴァロン, Hepburn: Avaron), also known as Gate to Avalon, is a 2001 Polish-language science fiction drama film directed by Mamoru Oshii and written by Kazunori Itō. An international co-production of Japan and Poland, the film stars Małgorzata Foremniak as Ash, a player in an illegal virtual reality video game whose sense of reality is challenged as she attempts to unravel the true nature and purpose of the game.

Avalon was filmed in Wrocław, Nowa Huta, the Modlin Fortress and Warsaw. The 2009 film Assault Girls, which was written and directed by Oshii, is a stand-alone sequel set in the same fictional universe as Avalon.
