young sheldon cast

The main Young Sheldon cast centers on the Cooper family and a few key supporting characters, especially across its full 7-season run.

Main Cooper family

  • Iain Armitage as Sheldon Lee Cooper, the young genius whose childhood in East Texas sets up the events of The Big Bang Theory.
  • Zoe Perry as Mary Cooper, Sheldon’s deeply religious but fiercely protective mother.
  • Lance Barber as George Cooper Sr., Sheldon’s often-overwhelmed but caring father and Medford High football coach.
  • Montana Jordan as George “Georgie” Cooper Jr., Sheldon’s older brother, more street-smart than book-smart.
  • Raegan Revord as Missy Cooper, Sheldon’s twin sister, socially sharper and often the emotional glue of the siblings.
  • Annie Potts as Connie “Meemaw” Tucker, Sheldon’s fun, sharp-tongued grandmother who runs a laundromat and later a gambling room.

Later-season and narration roles

  • Jim Parsons as adult Sheldon Cooper (narrator), linking Young Sheldon directly to The Big Bang Theory and occasionally appearing on-screen in framing scenes.
  • Emily Osment as Mandy McAllister, introduced later as Georgie’s older love interest who becomes central to his story as the series progresses.

Notable recurring characters

  • Wallace Shawn as Professor John Sturgis, Sheldon’s first real mentor in theoretical physics and one of Meemaw’s love interests.
  • Matt Hobby as Pastor Jeff Difford, the upbeat pastor at the Coopers’ Baptist church.
  • Ryan Phuong as Tam Nguyen, Sheldon’s early best friend in high school.
  • McKenna Grace as Paige Swanson, another child prodigy whose life contrasts with Sheldon’s and recurs throughout key episodes.
