Complete cast breakdown of Mayor of Kingstown Season 4: Who plays whom and where you've seen them before?

Mayor of Kingstown season 4 is the upcoming installment of the thriller television series created by Taylor Sheridan and Hugh Dillon. While set in a fictional region, the story is based on real-life dynamics seen in prison towns. The season is set to premiere in the United States on Sunday, October 26, 2025. It will stream exclusively on Paramount+, with new episodes dropping weekly on Sunday nights.

The series explores the dark realities of the American prison system and its impact on a small Michigan town. The McLusky family serves as power brokers, navigating complex relationships between law enforcement, inmates, politicians, and gangs, as they attempt to bring a fragile sense of order to a community built around incarceration. The show delves into themes of systemic corruption, inequality, and survival in a place where prisons dominate every aspect of life.

Season 4 of Mayor of Kingstown continues the series’ shift stateside, with filming centered around Pittsburgh, Pennsylvania, and its suburbs—particularly Braddock, Clairton, West Mifflin, Elizabeth, West Elizabeth, and Jefferson Hills. The production also made use of industrial settings, such as the Carrie Furnace site in Homestead for "Tent City" sequences and Pittsburgh's Mon Valley Works (which include the Clairton Works, Edgar Thomson Works, and Irvin Works).
