Justified is an American neo-Western crime drama television series that premiered on March 16, 2010, on the FX network. Developed by Graham Yost, it is based on Elmore Leonard's stories about the character Raylan Givens, particularly "Fire in the Hole". Timothy Olyphant portrays Raylan Givens, a tough deputy U.S. Marshal enforcing his own brand of justice. The series revolves around the inhabitants and culture in the Appalachian mountains area of eastern Kentucky, specifically Harlan County where many of the main characters grew up. It also features Lexington, Kentucky, where the local U.S. Marshals office is situated. The series, comprising 78 episodes, was aired over six seasons and concluded on April 14, 2015.

Justified received critical acclaim throughout most of its run and has been listed by several publications as one of the best shows of the 2010s. Its acting, directing, art direction, and writing were praised, as were the performances of Olyphant and Walton Goggins. Justified was nominated for eight Primetime Emmy Awards, with two wins, for Margo Martindale's performance as Mags Bennett and Jeremy Davies' performance as Dickie Bennett.

In January 2022, FX announced Justified: City Primeval, a limited sequel series with Olyphant reprising his role as Raylan Givens. It premiered on July 18, 2023, and ended on August 29, 2023.
