Kevin Costner’s John Dutton may have moseyed on into the sunset. But the Yellowstone patriarch’s spirit still lingers over the series’ various spinoffs, one of which is mere months away from debuting.
The upcoming Y: Marshals — no relation to Y: The Last Man — will center on Luke Grimes’ Kayce Dutton, John’s youngest son. Yellowstone’s fifth and final season ended with Kayce selling off a large portion of the ranch. And, as its title implies, the spinoff will see him stepping into a new career as a U.S. Marshal.
Yellowstone creator Taylor Sheridan will serve as executive producer, as will SEAL Team veteran Spencer Hudnut, who will take the reins as showrunner.
So, when is Y: Marshals premiering? And who’s in the cast? Read on as we answer these questions and more.
According to the show’s official logline, Y: Marshals will find Kayce Dutton joining “an elite unit of U.S. Marshals, combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence.”
Is it really called Y: Marshals?
It could be, but Paramount has made it clear that Y: Marshals is a working title.
Who’s in the cast of Y: Marshals?
Joining Grimes will be an ensemble of new characters and returning favorites from Yellowstone.
One of the more notable names returning from Yellowstone is Gil Birmingham’s Thomas Rainwater, the casino magnate and leader of the Broken Rock Reservation. Mo Brings Plenty will also return as Mo, Rainwater’s lethal right-hand man.
Also returning? Tate Dutton (Brecken Merrill), the son of Kayce Dutton. Curiously absent from the show’s cast list — so far, at least — is Kayce’s wife and Tate’s mother, Monica, as played by Kelsey Asbille.
In early August, Entertainment Weekly confirmed that Logan Marshall-Green would join the cast as Pete Calvin, a military veteran whom Kayce befriended during his time in the Navy SEALs. Marshall-Green has been acting onscreen for more than two decades now, and is currently gearing up for a supporting role in Christopher Nolan’s The Odyssey.
Arielle Kebbel (Rescue: HI-Surf), Ash Santos (Mayor of Kingstown), and Tatanka Means (Killers of the Flower Moon) have each been cast as Kayce’s fellow marshals, while longtime character actor Brett Cullen (Winning Time) will recur on the series as Harry Gifford, the head of the U.S. Marshals in Montana.
How many episodes will there be of Y: Marshals?
Y: Marshals was given a 13-episode run by CBS.
Is there a Y: Marshals release date?
Y: Marshals will premiere midway through CBS’s 2025-2026 broadcast season. As of now, episodes are slated to air on Sunday nights at 9 p.m. ET.
