September is the busiest TV month of the year and it isn’t close. August handed us a big premiere every week or so. September puts three on the same Wednesday. I was recently telling my kids about how September used to be the signal of new TV every year after a summer of reruns, and it kind of blew their mind.
So here’s the rundown of new TV shows in September 2026 actually worth your time. Six of them. If you want every premiere date including the network returns and the reality stuff, the 2026 TV show release dates calendar has the full list.
| Date | Show | Platform |
|---|---|---|
| September 3 | The Gentlemen Season 2 | Netflix |
| September 16 | Neagley | Prime Video |
| September 16 | Slow Horses Season 6 | Apple TV |
| September 16 | South Park Season 29 | Comedy Central |
| September 18 | MobLand Season 2 | Paramount+ |
| September 24 | A Different World | Netflix |
The Gentlemen Season 2
Premiere: September 3 | Platform: Netflix
Theo James and Kaya Scodelario are back as Eddie and Susie, and the operation has moved from a cannabis farm under an English estate to lakeside villas in Italy. Ray Winstone returns as Bobby Glass. Hugh Bonneville joins.
Season one took a while to find its footing and then got very good in the back half. Two and a half years is a long gap for a show that ran on momentum, so Italy is either a smart reset or a stall.
Guy Ritchie is still attached, which means you know the tone before you press play.
This is not on my must-see list right away, but it’s a good one to have when you are waiting for another episode of one of your favourites.
Neagley
Premiere: September 16 | Platform: Prime Video
Maria Sten gets her own show. Frances Neagley is a private investigator in Chicago, and she goes after the truth when a friend dies in an accident that doesn’t add up.
All eight episodes drop at once. Alan Ritchson guest stars, so the connection isn’t just on the poster.
Reacher season four wraps the same day, so Prime Video is handing you eight more hours the second you finish. If the spinoff sends you back to the source, the Jack Reacher books in order guide sorts out where to start.
I am a little suspect on this spinoff, but I will give it a try.
Slow Horses Season 6
Premiere: September 16 | Platform: Apple TV
Six episodes, weekly through October 21, pulling from Joe Country and Slough House in Mick Herron’s series.
Gary Oldman, Kristin Scott Thomas and Jack Lowden are back, with Jonathan Pryce and Hugo Weaving in the mix and Lenny Rush joining. The Slow Horses spend this one on the run after Diana Taverner drags them into a revenge job.
Five seasons in and it still hasn’t dipped.
Slow Horses is one of my favourite shows every year. And you notice I say, every year. No waiting and waiting for more. I appreciate that.
South Park Season 29
Premiere: September 16 | Platform: Comedy Central, next day on Paramount+
Twenty-nine seasons. New episodes air every other week rather than weekly, and Paramount+ has them the next day in Canada.
The show still works best when it goes straight at whatever happened that week, and there’s no sign that’s changing.
MobLand Season 2
Premiere: September 18 | Platform: Paramount+
Ten episodes. Tom Hardy is back as Harry Da Souza, with Pierce Brosnan and Helen Mirren, and the Harrigans are trying to look united while rivals pick at a cracking empire.
There was noise this summer about whether Hardy would return at all. He does.
Season one was Guy Ritchie doing what Guy Ritchie does, with Mirren taking every scene she was in. If season two gives her more to do, it earns the ten hours.
I really liked Season one and the theme song is on constant repeat on my phone. Can’t wait.
A Different World
Premiere: September 24 | Platform: Netflix
Hillman College is back. Maleah Joi Moon plays Deborah Wayne, the youngest daughter of Dwayne Wayne and Whitley Gilbert, and she’s a freshman.
Jasmine Guy, Kadeem Hardison, Darryl M. Bell, Cree Summer, Jada Pinkett Smith and Jennifer Lewis all return. Debbie Allen executive produces and directs the premiere. Ten episodes.
Most legacy revivals bring back a couple of familiar faces and hope that’s enough. This one brought back six of them plus the director who shaped the original.
I don’t know if I will watch this show. I just felt like adding it because I really did like the original way back in the day.
Six shows worth clearing an evening for. I update the Power Rankings: Top 10 TV Shows of 2026 every month, so whatever survives September shows up there.
