The third season of the American superhero streaming television series Titans premiered on HBO Max on August 12, 2021, and concluded on October 21, 2021, consisting of 13 episodes. It was executive produced by Akiva Goldsman, Geoff Johns, Greg Walker, Greg Berlanti, Sarah Schechter, and Richard Hatem, with Walker serving as showrunner for the third consecutive season. Developed by Goldsman, Johns, and Berlanti, the series is based on the DC Comics team Teen Titans. Brenton Thwaites, Anna Diop, Teagan Croft, Ryan Potter, Conor Leslie, Curran Walters, Joshua Orpin, Minka Kelly, and Alan Ritchson return to the main cast from the previous season, joined by season 2 guest star Damaris Lewis and series newcomers Savannah Welch and Vincent Kartheiser. It is the final season to feature longtime cast member Ritchson, who exited the series after appearing in the first two seasons.
In the third season, the Titans team of Dick Grayson (Thwaites), Kory Anders (Diop), Gar Logan (Potter), Conner (Orpin), Dawn Granger (Kelly), and Hank Hall (Ritchson) travel to Gotham City after learning that their former teammate Jason Todd (Walters) was murdered. Tasked with protecting the city in the absence of Bruce Wayne (Iain Glen), the Titans find themselves targeted by a resurrected Jason, now calling himself Red Hood. Dick, working alongside former vigilante partner and love interest Barbara Gordon (Welch) in her new role as police commissioner, is forced to receive assistance from incarcerated criminal Jonathan Crane (Kartheiser) in stopping Jason. Further tensions emerge when Kory’s sister Blackfire (Lewis) takes up residence with the team, despite conflict between her and Kory. Meanwhile, Titan Rachel Roth (Croft) trains with the Amazons in Themyscira as she attempts to resurrect fallen teammate Donna Troy (Leslie).
