Young Sheldon is an American sitcom television series created by Chuck Lorre and Steven Molaro that aired on CBS from September 25, 2017, to May 16, 2024. The series is a spin-off prequel to The Big Bang Theory that takes place during the late 1980s and early-to-mid-1990s, and follows child prodigy Sheldon Cooper as he grows up with his family in East Texas. Iain Armitage stars as Sheldon, alongside Zoe Perry, Lance Barber, Montana Jordan, Raegan Revord, and Annie Potts. Jim Parsons, who portrayed the adult Sheldon Cooper on The Big Bang Theory, narrated the series and served as an executive producer.

In November 2023, CBS announced that the series would end after its seventh season. The one-hour series finale aired on May 16, 2024. The series received positive reviews from critics.
