In 2013, Sheridan began work on the series, having recently grown tired of acting and switching to screenwriting. Having lived in the rural parts of states such as Texas and Wyoming, Sheridan set the series in Montana and set the first scripts in Livingston. Sheridan initially pitched the series to HBO, but the network declined. The series follows the Dutton family, owners of the largest ranch in Montana, the Yellowstone Dutton Ranch, commonly called "the Yellowstone". The plot revolves around family drama at the ranch and the bordering Broken Rock Indian Reservation, Yellowstone National Park, and developers. In May 2017, Paramount Network announced that it had greenlit its first scripted series, Yellowstone. Paramount issued a series order for a first season consisting of ten episodes. The series was set to be written, directed and executive-produced by Sheridan.

A prequel series titled 1883 (2021–2022) was announced following a five-year deal signed by Sheridan with ViacomCBS and MTV Entertainment Group. The series focuses on a generation of the Dutton family during the Old West as they undertake the arduous journey across the country before settling the land that would become the Yellowstone Ranch. A second prequel series titled 1923 (2022–present) focuses on an intervening generation of the Dutton Family during the time of Western Expansion, Prohibition, and the Great Depression. A third planned spin-off titled Lawmen: Bass Reeves is in development and will focus on the life of the titular character. A fourth planned spin-off titled 6666 is also in development and is set in the present day on the Four Sixes Ranch in Texas. A further fifth spin-off titled 1944 was confirmed by Paramount in early 2023.
