Young Sheldon Complete Cast & Character Guide (Every Season)

The Young Sheldon cast teams up to take fans back to Sheldon Cooper’s childhood with his family in Texas, while also featuring a string of supporting characters that make the socially inept genius’ story much more exciting. In an effort to capitalize on the popularity of The Big Bang Theory, the sitcom’s first and only spin-off premiered in 2017. For two years, the shows aired back-to-back, but since its parent series wrapped up its run in 2019, Young Sheldon has been standing on its own. The events of Young Sheldon take place around two decades before the beginning of The Big Bang Theory.
