There is no official Prison Break Season 8 as of now. The series originally ran for 4 seasons (2005–2008), followed by a revival Season 5 in 2017. Any references to “Season 8” are likely fan-made, mislabeled content, or a fictional project.
Hulu has greenlit a new series set within the same fictional universe as the original show. This project, led by Mayans M.C. co-creator Elgin James, is described as a "soft reboot" rather than a direct Season 6 or Season 8.
