Fox is expanding the long-running Family Guy universe with a new animated series centered on its most notorious toddler. The network has ordered two seasons of “Stewie,” a spinoff built around Stewie Griffin, the foul-mouthed baby of the family.
The project is scheduled to premiere during the 2027–2028 broadcast season, with episodes airing on Fox and streaming the next day on Hulu in the United States. Family Guy mastermind Seth MacFarlane co-creates the series alongside longtime writer-producer Kirker Butler. MacFarlane will continue voicing Stewie and will serve as an executive producer, with Butler acting as showrunner. Producer Kara Vallow also joins the creative team.
The spinoff reportedly centers on Stewie after he is expelled from his original preschool and forced to enroll in a new one that is far less prestigious. The setting introduces a new group of eccentric classmates, including an unusual class pet described as a 75-year-old turtle. True to form, the seemingly mundane school environment quickly becomes a launchpad for Stewie’s elaborate schemes and science-fiction misadventures. The character uses his trademark gadgets and inventions to trigger adventures that stretch across space and time.
Stewie has been a central figure in Family Guy since the animated sitcom premiered on Fox in 1999. Created by MacFarlane, the series follows the dysfunctional Griffin family in the fictional Rhode Island town of Quahog. Stewie, the youngest member of the family, is portrayed as a hyper-intelligent baby with an aristocratic accent, a fondness for elaborate technology and an often-stated ambition for world domination. His dynamic with the family’s talking dog Brian has produced some of the show’s most acclaimed episodes, including the long-running “Road to…” adventure installments.
The upcoming series becomes the second television spinoff from the franchise following The Cleveland Show, which aired from 2009 to 2013. Fox’s early two-season commitment underscores the continued strength of the Family Guy brand after more than two decades on television.
