Young Justice: Outsiders is the third season of the American animated superhero series Young Justice, developed by Brandon Vietti and Greg Weisman. The series follows the lives of teenage superheroes and sidekicks who are members of a covert operation group, referred to simply as "The Team", that acts as a young counterpart to the famous adult team, the Justice League. In the second season, Invasion, the Reach revealed the existence of the meta-gene. Following on from these events, the third season focuses on the Team battling metahuman trafficking as various nations and organizations have started participating in such activities. It also features the superhero team Outsiders.

Young Justice originally aired on Cartoon Network for two seasons from 2010 to 2013, before being cancelled due to low toy sales and Mattel pulling funding. Following a strong fan campaign and high viewership ratings on Netflix, the series was officially renewed for a third season by Warner Bros. in November 2016. Development on Outsiders began the next month. By July 2017, it was split into two separate sections/arcs, each consisting of 13 episodes, making a total of 26 for the whole season.
