Nirvanna the Band the Show the Movie is a 2025 Canadian time travel mockumentary-adventure film directed by Matt Johnson from a screenplay by Johnson and Jay McCarrol. The film stars Johnson and McCarrol as fictionalised versions of themselves in a band called "Nirvanna the Band" as they attempt to book a gig at the Rivoli, a bar and restaurant in Toronto, despite the fact that they have never actually written or recorded a single song, nor taken any steps to contact the Rivoli's management about booking a show. A publicity stunt gone wrong accidentally sends Matt, Jay, and their friend/cameraman Jared back in time to the year 2008, leaving them stranded unless they can find a way to get back to the future.

The film is based on Johnson and McCarrol's 2007–2009 web series Nirvana the Band the Show, as well as its 2017–2018 sequel television series Nirvanna the Band the Show.
