The core main cast of That ’70s Show centers on a tight-knit group of teens in Point Place, Wisconsin, plus their families and a few standout adults.

Main teen group

  • Topher Grace as Eric Forman – Sarcastic, nerdy, well‑meaning kid who is the emotional center of the show for most of its run.
  • Mila Kunis as Jackie Burkhart – Image‑obsessed, dramatic cheerleader who slowly grows from shallow to more self‑aware.
  • Ashton Kutcher as Michael Kelso – Good‑looking, dim‑witted goof whose bad decisions drive a lot of the comedy.
  • Danny Masterson as Steven Hyde – Eric’s rebellious best friend, anti‑establishment, with a laid‑back, cynical attitude.
  • Laura Prepon as Donna Pinciotti – Smart, independent girl next door and Eric’s on‑again, off‑again love interest.
  • Wilmer Valderrama as Fez – Foreign exchange student whose real name and origin country are an ongoing joke.

These six form the iconic basement circle that most people think of when they say “cast of That ’70s Show.”

The Forman family

  • Debra Jo Rupp as Kitty Forman – Eric’s warm, anxious mom with the unforgettable laugh, often trying to keep the household together.
  • Kurtwood Smith as Red Forman – Eric’s strict, no‑nonsense dad, famous for his constant threats and deadpan insults.
  • Lisa Robin Kelly (later Christina Moore) as Laurie Forman – Eric’s manipulative, trouble‑making older sister.

The Pinciottis and other key adults

  • Don Stark as Bob Pinciotti – Donna’s slightly clueless, often cringey dad with very 70s fashion and a big personality.
  • Tanya Roberts as Midge Pinciotti – Donna’s free‑spirited mother, into every self‑help fad of the decade.
  • Tommy Chong as Leo – The perpetually spaced‑out hippie who employs Hyde at the Photo Hut and steals scenes whenever he appears.
  • Josh Meyers as Randy Pearson – Introduced late in the series as a new member of the friend group in the final season.
