The queen of “30 Rock” could be making her return to 30 Rock.

A source told The Post that Tina Fey is being courted to take over as executive producer of “Saturday Night Live” when creator and current executive producer Lorne Michaels departs.

So far, Michaels, 78, has not formally announced any intention to leave the weekly sketch comedy series he created in 1975. In an interview with the New York Times last year, the producer said, “I have no plans to retire.”

A year before that, however, he left the door open to a new phase, away from Studio 8H.

Michaels told Gayle King on “CBS Mornings,” “I think I’m committed to doing the show until its 50th anniversary, which is in three years … I’d like to see that through and I have a feeling that would be a really good time to leave.”

The 50th season of “Saturday Night Live” is set to start in fall 2024, when the all-powerful Michaels will turn 80 years old. That will also coincide with another presidential election — when “SNL” reliably gets its best ratings — likely featuring Donald Trump.

Fey, one of the greatest talents to ever come out of NBC, is considered by many in the industry to be the leading candidate — some say the only candidate — to take the helm at “Saturday Night Live.”

“I would be surprised if it wasn’t her,” a source said. “Seth Meyers has his own show. Seth Rogen and Evan Goldberg won’t come here. Judd Apatow passed [on the job] years ago. Amy Poehler has her own stuff. Bill Hader is directing a movie. Kate McKinnon is too hot.”

Online speculation that Fey, 53, would snag the “SNL” gig has been swirling for the past few years. Meyers has also been suggested as a possibility. But a source said the Fey move is coming closer to reality.

Many fellow showrunners believe that the job is Fey’s if she wants it and that frequent collaborator Robert Carlock, who worked with her on “30 Rock,” “Unbreakable Kimmy Schmidt,” “Girls5eva,” “Mr. Mayor” and other series, would come along to “SNL,” too.

“She doesn’t move without him,” a source said.

For Fey, who lives in Manhattan with her husband, Jeff Richmond — a composer, producer and director — and their two daughters, the “SNL” job would also suit her family life.

“I think she’d do it,” a source said. “It would keep the husband employed and the kids in school here.”

Steve Higgins has two jobs. At 4:30 every day, 4 days a week, Steve announces The Tonight Show, sticks around to play Jimmy Fallon’s straight man, and then runs back upstairs at 30 Rock to keep working on that week’s Saturday Night Live. At SNL, he's in charge of the writers' room and, alongside Lorne Michaels, makes all the big decisions about the shape of the show, and the cast.

Gillis was reportedly cast, in part, as a way to counteract a perception of liberal bias—and to boost the show’s appeal with conservatives.

Sources tell Variety that SNL and Lorne Michaels had hoped to add a comedian to season 45’s cast who might raise the show’s stock with conservative viewers, despite a historic perception that the show has a liberal bias, exacerbated as Alec Baldwin and various cast members make hay of Donald Trump and his administration.
