We all know Young Sheldon as the witty, endearing, sometimes awkward story of a boy genius navigating life in small-town Texas. But behind every perfectly timed one-liner and tear-jerking moment is a brilliant cast that brings the Cooper family—and everyone around them—to life.
So, who are the stars of Young Sheldon? Let’s dive into the full cast list, their roles, and what makes them the magic behind the scenes.
👦 Who Plays Young Sheldon?
Iain Armitage as Sheldon Cooper
At the heart of the show is Iain Armitage, who portrays a younger version of the iconic Sheldon Cooper. Iain nails the quirky genius vibes with uncanny precision. You might also recognize him from Big Little Lies, where he played Ziggy Chapman.
What sets Iain apart is his ability to channel Sheldon’s intellect, awkwardness, and unfiltered honesty—all while being incredibly likable. That’s not easy, folks!
👨 The Cooper Family Cast Breakdown
Lance Barber as George Cooper Sr.
Playing Sheldon’s father, Lance Barber brings depth to George Sr.—a character who, in The Big Bang Theory, is mostly remembered through vague anecdotes. In Young Sheldon, we get to see a hardworking, often misunderstood dad trying to do right by his gifted son.
You may also remember Lance from roles in The Comeback and It’s Always Sunny in Philadelphia.
Zoe Perry as Mary Cooper
Here’s a cool trivia bit: Zoe Perry, who plays Mary Cooper (Sheldon’s mom), is actually the real-life daughter of Laurie Metcalf—the actress who played adult Mary in The Big Bang Theory. Talk about a seamless transition!
Zoe brings a perfect blend of fierce love, Christian values, and exhausted mom energy to the role.
Montana Jordan as George “Georgie” Cooper Jr.
Sheldon’s older brother Georgie is played by Montana Jordan. He’s the polar opposite of Sheldon—more about girls, money, and pickup trucks than physics and quantum mechanics. Montana brings a lot of heart to Georgie, making him way more than just the “dumb older brother.”
Raegan Revord as Missy Cooper
Sheldon’s twin sister Missy is played by the hilariously sharp Raegan Revord. She steals scenes with her sarcasm and relatability, and honestly, her timing is gold. She balances Sheldon’s overly literal behavior with a down-to-earth sense of humor and sass.
🎓 Supporting Cast Members Who Deserve a Shout-Out
Annie Potts as Meemaw (Connie Tucker)
Everyone loves a good grandma—and Annie Potts delivers as Meemaw. She’s the poker-playing, whiskey-sipping, wisecracking matriarch of the Cooper clan. You might know Potts from classics like Ghostbusters or Designing Women, but her role in Young Sheldon is one of her most beloved.
Matt Hobby as Pastor Jeff
As the local pastor and Mary’s boss at church, Pastor Jeff (played by Matt Hobby) adds a mix of comedy and awkward faith-based conflict. His character has become a fan favorite for his well-meaning but often clueless moments.
Emily Osment as Mandy McAllister
Originally introduced in later seasons, Emily Osment plays Mandy, Georgie’s older girlfriend (and eventual mother of his child). You’ll
