Sonic the Hedgehog 2 is a 2022 action-adventure comedy film based on the video game series published by Sega, and the sequel to Sonic the Hedgehog (2020). Directed by Jeff Fowler and written by Pat Casey, Josh Miller, and John Whittington, the film stars Ben Schwartz, Jim Carrey, James Marsden, Tika Sumpter, Natasha Rothwell, Adam Pally, Lee Majdoub, and Colleen O'Shaughnessey reprising their roles, with Idris Elba and Shemar Moore joining the cast. In the film, after settling in Green Hills, Sonic tries to prove himself as a hero, but his big test comes when the dastardly Dr. Robotnik returns, alongside his new rival, Knuckles the Echidna, in search of the Master Emerald. Sonic teams up with his own sidekick Tails to embark on a journey to find the Emerald before Dr. Robotnik does.

Following the success of the first film, Paramount Pictures announced the sequel in May 2020, with Fowler returning as director, Casey and Josh Miller returning as writers, and Schwartz, Carrey, and the rest of the cast reprised their roles. 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, and in the United States on April 8, by Paramount Pictures and Sega Sammy Group. Like its predecessor, the film set several box office records and received generally positive reviews for its action sequences, humour, and performances, but criticized its screenplay, runtime and pacing. Many critics considered the film an improvement over the original. It grossed over $405 million worldwide, surpassing its predecessor and becoming the highest-grossing video game film in the United States until the following year's The Super Mario Bros. Movie.

Sonic the Hedgehog 3 is scheduled for 2024, while Knuckles, a spin-off series starring Elba, is scheduled to premiere on Paramount+ in late 2023.
