Resident Alien is back with its fourth season—and this time, it’s airing on a new network. After three successful seasons on Syfy, the hit sci-fi comedy has moved to USA Network, where new episodes air Fridays at 11 p.m. ET, with a simultaneous broadcast on Syfy.
Alan Tudyk returns as Harry, the alien doctor stuck on Earth, whose situation gets even messier this season. Season 4 picks up with Harry and his alien baby, Bridget, trapped in a high-security prison on the Grey Moonbase. Meanwhile, back on Earth, a shapeshifting alien impersonates Harry, creating chaos in his absence.
Resident Alien Season 4 premiered on June 6, 2025, and follows a weekly release model. New episodes become available to stream one week after their broadcast on both USANetwork.com and Peacock, offering fans flexibility in how they watch. The season includes ten episodes, airing weekly through August 8.
The returning cast features Sara Tomko, Corey Reynolds, Alice Wetterlund, Levi Fiehler, and Elizabeth Bowen, with notable guest stars such as Jewel Staite, Stephen Root, Terry O’Quinn, Gary Farmer, and Jenna Lamia adding fresh energy to the story.
With its mix of mystery, dark humor, and sci-fi intrigue, Resident Alien continues to deliver sharp, unexpected turns. Season 4 raises the stakes as Harry tries to escape the moonbase, protect his child, and take back his life from a dangerous doppelgänger. Whether you’re watching live on USA or catching up later on Peacock, this season promises a wild ride.
