Stewie Griffin gets his own show! Seth MacFarlane voices the evil genius in a new Family Guy spinoff series, premiering 2027-28 on Fox.
- March 13, 2026
AceShowbiz - Nearly twenty years after the debut of the first spinoff, Fox has greenlit a new animated series centered on the youngest Griffin, Family Guy’s Stewie. The network has committed to a two-season run for Stewie, which is scheduled to premiere during the 2027-28 television season.
The new series is developed by Seth MacFarlane, creator of Family Guy, alongside Kirker Butler, a seasoned writer and producer on the original show. Production will be handled by 20th Television Animation, the same studio behind the parent series. MacFarlane will continue to voice the lead character, maintaining continuity with the beloved animated universe.
This marks the second official spinoff of Family Guy, following The Cleveland Show, which aired for four seasons from 2009 to 2013. The upcoming Stewie series is positioned to run concurrently with the final year of Family Guy’s current four-season order, which concludes in 2028-29. This timeline also aligns with Fox’s agreements for other flagship animated series such as Bob's Burgers, The Simpsons, and the recently revived American Dad.
Kirker Butler, who has also contributed to MacFarlane’s Peacock series Ted and Hulu’s Only Murders in the Building, will serve as showrunner. He will executive produce alongside MacFarlane and Kara Vallow, helping to steer the project creatively.
The storyline for Stewie follows the mischievous infant after he is expelled from his previous preschool and forced to attend a less prestigious institution. There, he encounters unfamiliar peers and an elderly class turtle with unconventional theories on various topics. Initially, everyone is unhappy, but Stewie soon uses his inventive gadgets to transform their dull school days into wild and surreal adventures across space and time.
This development was first reported by Deadline, highlighting Fox’s ongoing commitment to expanding the Family Guy franchise with fresh and engaging content. Fans can look forward to a new chapter in Stewie’s story when the series launches in the 2027-28 season, continuing the legacy of one of television’s most iconic animated characters.
