The fifth season of Samurai Jack is the final season of the animated series. This season of Samurai Jack follows Jack on a journey that concludes his story. It premiered on the Toonami programming block of Adult Swim on March 11, 2017, and concluded its run on May 20, 2017. The announcement of the season came in December 2015, eleven years since the series was originally concluded on Cartoon Network. Genndy Tartakovsky, the series' creator, returned as a director, writer, and storyboarder for this season. The season received universal acclaim from both critics and fans, praising it for its visuals as well as its more intense and mature tone, but was critiqued towards the finale with some calling it rushed and feeling the romance between Jack and Ashi was unnecessary.
