Zathura: A Space Adventure (also known simply as Zathura) is a 2005 American science fiction adventure film directed by Jon Favreau. It is an adaptation of the 2002 children’s book Zathura by Chris Van Allsburg, author of Jumanji. Unlike the book, the film contains no direct connection to Jumanji, though it was marketed as taking place within the same fictional universe as the 1995 film. It is considered the second installment of the Jumanji franchise. The film stars Josh Hutcherson, Jonah Bobo, Dax Shepard, Kristen Stewart, and Tim Robbins.

The story revolves around brothers Walter and Danny Budwing (portrayed by Hutcherson and Bobo respectively), who play a mysterious board game they find in the basement of their house. The game teleports Walter, Danny, and their older sister Lisa (Stewart) into outer space where they encounter an astronaut (Shepard), who mentors the siblings on survival and finishing the game so they can return home.

The film was shot in Los Angeles and Culver City, California, and was released on November 11, 2005 by Columbia Pictures. It received positive reviews from critics.
