The Short Answer
The Westies is not an official spinoff of Mayor of Kingstown. The two shows air on different networks — Mayor of Kingstown is a Paramount+ series created by Taylor Sheridan, while The Westies is an MGM+ series created by Chris Brancato (Narcos, Godfather of Harlem) and Michael Panes. There's no shared production banner or narrative continuity between them. The confusion comes from something else: real, if smaller, overlapping DNA.
Where the Confusion Comes From
The clearest link is actor Hamish Allan-Headley, who played the series regular role of Robert Sawyer on Mayor of Kingstown from its launch, and now plays a young John Gotti as a series regular on The Westies. That's a real crossover in casting, not just a coincidence of genre — and it's likely the main reason search engines and fans have started pairing the two shows together.
Beyond that one actor, the link is more about genre and timing than continuity: both shows belong to a wave of "industrial grit" crime dramas — prestige television built around systemic corruption and territorial power struggles — that has become a dominant subgenre in the mid-2020s.
What The Westies Is Actually About
The Westies dramatizes the real Irish-American organized crime group that controlled Manhattan's Hell's Kitchen from the mid-1960s through the late 1980s. The series uses the real 1980s construction of the Jacob K. Javits Convention Center — built on the Westies' home turf — as a central narrative engine, showing how organized crime intersected with the politics of a major public works project.
The Cast
The Westies has assembled a heavyweight ensemble: J.K. Simmons headlines, alongside Tom Brittney, Titus Welliver, Jessica Frances Dukes, Stanley Morgan, Sarah Bolger, Allen Leech, Vincent Walsh, Hilary McCormack, and Hamish Allan-Headley as the young John Gotti.
The Bottom Line
If you came looking for a Mayor of Kingstown universe expansion, The Westies isn't it — there's no shared showrunner, network, or storyline. But if what actually drew you in was the genre (corrupt power, organized crime, a gritty 1980s setting), The Westies delivers a similar tone with its own self-contained story, and it's worth watching on its own terms rather than as an extension of Sheridan's world.
The Real Connection, Summarized
The Westies is not an official Mayor of Kingstown spinoff. They air on different networks with different creators — Mayor of Kingstown is a Paramount+ series from Taylor Sheridan, while The Westies is an MGM+ series from Chris Brancato and Michael Panes. The confusion comes from actor Hamish Allan-Headley, who played a series regular on Mayor of Kingstown and now plays a young John Gotti on The Westies, plus the two shows sharing the same "industrial grit" crime-drama genre.
