Knuckles is an American television series created by John Whittington and Toby Ascher for the streaming service Paramount+, based on the Sonic the Hedgehog video game series published by Sega. It is a spin-off of the Sonic the Hedgehog film series and the first live-action Sonic television series. The series serves as a bridge between the events of the films Sonic the Hedgehog 2 (2022) and Sonic the Hedgehog 3 (2024), and follows Knuckles the Echidna as he trains deputy sheriff Wade Whipple in the ways of the Echidna warrior. Whittington was head writer, with Ascher as showrunner.

Idris Elba reprised his voice role as Knuckles from the film series and stars alongside Adam Pally, reprising his role as Wade. The series was announced in February 2022 during a ViacomCBS investor event, with Elba on board with the project. Production began in London, England, in April 2023, with Sonic film director Jeff Fowler directing the pilot and further casting announced. Ged Wright, Brandon Trost, Jorma Taccone, and Carol Banker directed the following episodes. Tom Howe composed the score.

Knuckles premiered on April 26, 2024, with all six episodes. Over its premiere weekend, it became the most-watched original series on Paramount+. It received generally positive reviews from critics, with praise directed towards the action sequences and Elba and Pally's performances, although some criticized the show for its writing and underdeveloped characters.
