Spider-Man: Into the Spider-Verse is a 2018 American animated superhero film featuring the Marvel Comics character Miles Morales / Spider-Man, produced by Columbia Pictures and Sony Pictures Animation in association with Marvel Entertainment, and distributed by Sony Pictures Releasing. It is the first animated film in the Spider-Man franchise and the first film in the Spider-Verse franchise, which is set in a shared multiverse of alternate universes called the "Spider-Verse". Directed by Bob Persichetti, Peter Ramsey, and Rodney Rothman from a screenplay by Phil Lord and Rothman, it stars Shameik Moore as Morales, alongside the voices of Jake Johnson, Hailee Steinfeld, Mahershala Ali, Brian Tyree Henry, Lily Tomlin, Luna Lauren Vélez, John Mulaney, Kimiko Glenn, Nicolas Cage, and Liev Schreiber. The film's story follows Miles as he becomes the new Spider-Man and joins other Spider-People from various parallel universes who team up to save New York City from the Kingpin.

Plans for an animated Spider-Man film by Phil Lord and Christopher Miller were leaked in 2014 and announced in April 2015. Persichetti, Ramsey and Rothman joined over the next two years, with Moore and Schreiber cast in April 2017. Lord and Miller wanted the film to have a unique style, combining computer animation with hand-drawn comic techniques inspired by the work of Miles Morales co-creator Sara Pichelli. The film required the largest crew of animators used by Sony Pictures Animation on a feature film.

The film premiered at the Regency Village Theater in Los Angeles on December 1, 2018, and was theatrically released in the United States on December 14. The film grossed $394 million worldwide against a $90 million budget and received critical acclaim. The film won Best Animated Feature at the 91st Academy Awards, and numerous other accolades. Into the Spider-Verse has since been regarded as one of the greatest and most impactful animated films, particularly for its groundbreaking achievement in animation, with filmmakers and animation peers praising its aesthetics and acknowledging its influence on subsequent animated productions.

A sequel, Spider-Man: Across the Spider-Verse, was released in 2023 to similar critical acclaim and greater commercial success, while a third film, Spider-Man: Beyond the Spider-Verse, is scheduled for a 2027 release. A spin-off film focused on female Spider-related characters is in development.
