The main cast of That ’70s Show centers on a tight group of teens in Point Place, Wisconsin, plus their parents and neighbors.

Core teen group

  • Topher Grace as Eric Forman – The geeky, sarcastic leader of the friend group and the main point-of-view character for most of the series.
  • Mila Kunis as Jackie Burkhart – A status-obsessed, dramatic cheerleader who starts out as Kelso’s girlfriend and evolves into a more layered character.
  • Ashton Kutcher as Michael Kelso – Handsome but dim-witted, known for his goofy charm and physical comedy.
  • Danny Masterson as Steven Hyde – The cynical, conspiracy-loving rebel with a tough exterior and loyal streak.
  • Laura Prepon as Donna Pinciotti – Eric’s smart, independent neighbor and longtime love interest, often the most grounded one in the group.
  • Wilmer Valderrama as Fez – The foreign exchange student with an undefined home country, memorable for his accent and awkward romantic pursuits.

Parents and adults

  • Debra Jo Rupp as Kitty Forman – Eric’s warm, high-strung mom, known for her distinctive laugh and overprotective nature.
  • Kurtwood Smith as Red Forman – Eric’s strict, short-tempered dad with a tough-love approach and many iconic insults.
  • Don Stark as Bob Pinciotti – Donna’s affable, slightly clueless dad, a constant presence next door.
  • Tanya Roberts as Midge Pinciotti – Donna’s mother, portrayed as attractive, free-spirited, and a bit spacey in early seasons.

Other notable recurring cast

  • Lisa Robin Kelly / Christina Moore as Laurie Forman , Eric’s manipulative older sister (Kelly in early seasons, Moore later).
  • Tommy Chong as Leo , the spaced-out hippie who employs Hyde at the Foto Hut and becomes a fan-favorite comic character.
  • Josh Meyers as Randy Pearson , who joins the main ensemble in the final season after Eric’s departure.
