Ralph Breaks the Internet is a 2018 American animated comedy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. It is the sequel to the 2012 film Wreck-It Ralph. The film was directed by Rich Moore and Phil Johnston, and produced by Clark Spencer, from a screenplay written by Johnston and Pamela Ribon, and a story by Moore, Johnston, Ribon, Josie Trinidad, and Jim Reardon. John Lasseter, Jennifer Lee, and Chris Williams served as the film's executive producers. John C. Reilly, Sarah Silverman, Jack McBrayer, Jane Lynch, and Ed O'Neill reprise their character roles from the first film, and are joined by Gal Gadot, Taraji P. Henson, and Alfred Molina as part of the new cast, as well as Alan Tudyk, who voiced a new character in this film. In the film, Ralph (Reilly) and Vanellope von Schweetz (Silverman) must travel to the Internet to get a replacement for the Sugar Rush cabinet's broken steering wheel and prevent Mr. Litwak (O'Neill) from disposing of the game.

The first discussions about a sequel to Wreck-It Ralph began in September 2012, and the new installment went through three different scripts before the filmmakers settled on the final plot. When the film was officially announced in June 2016 as Ralph Breaks the Internet: Wreck-It Ralph 2, much of the original cast confirmed they had signed on, with new cast members added in 2018. It is Walt Disney Animation Studios' first computer-animated film sequel and is the first sequel from the studio to be created by the original film's creative team.

Ralph Breaks the Internet premiered in Hollywood, Los Angeles, on November 5, 2018, and was released in the United States on November 21. The film grossed over $529.3 million worldwide against its $175 million budget and received generally positive reviews from critics. The film was nominated for Best Animated Feature at the 91st Academy Awards, 76th Golden Globe Awards, 46th Annie Awards, and 24th Critics' Choice Awards.
