Benjamin Kirby "Ben" Tennyson, commonly known as Ben 10, is a superhero and the titular protagonist of the Ben 10 franchise. Created by Man of Action and produced by Cartoon Network Studios, he first appeared in the 2005 animated series Ben 10, following his journey through Ben 10: Alien Force (2008–2010), Ben 10: Ultimate Alien (2010–2012), Ben 10: Omniverse (2012–2014). The franchise was later rebooted in 2016, with Ben 10 (2016–2021), reimagining the character as a 10-year-old for a modern audience. Across these iterations, he matures from a reckless and adventurous child into a capable and responsible hero once he obtains the Omnitrix, a watch-like device which allows him to turn into various alien species.

Since his debut, Ben Tennyson has become one of Cartoon Network's most recognizable characters and has appeared in various media such as feature-length films, specials, comic books, video games, park attractions, books, game shows, plays, and attractions. He is voiced by Tara Strong as a child and Yuri Lowenthal as a teenager throughout the franchise.
