Sonic the Hedgehog 2 is a 2022 action-adventure comedy film based on the Sonic video game series. The second in the Sonic film series, it was directed by Jeff Fowler and written by Pat Casey, Josh Miller, and John Whittington. Ben Schwartz, James Marsden, Tika Sumpter, Colleen O'Shaughnessey and Jim Carrey reprise their roles, with Idris Elba joining the cast. In the film, Sonic the Hedgehog and his friend Tails embark on a journey to find the Master Emerald before their nemesis, Dr. Ivo Robotnik, and his accomplice, Knuckles the Echidna.

Following the success of Sonic the Hedgehog (2020), Paramount Pictures announced the sequel in May 2020, with Fowler, Casey, Miller and the cast returning. Filming took place from March to June 2021 in Vancouver and Hawaii. The film draws inspiration from the video games Sonic the Hedgehog 2 (1992), Sonic the Hedgehog 3 (1994), and Sonic & Knuckles (1994).

Sonic the Hedgehog 2 was theatrically released in several markets on March 30, 2022, in the United States on April 8, and in Japan on August 19. Like its predecessor, it set several box office records for a video game film and received positive reviews from critics, who praised the performances and action sequences but criticized the screenplay and runtime. It grossed $405.4 million worldwide. A spin-off series, Knuckles, premiered on Paramount+ on April 26, 2024, while a third film was released on December 20, 2024.
