-> '''Superman:''' I once thought I could protect the world by myself, but I was wrong. Working together, we saved the planet, and I believe that if we stay together as a team, we would be a force that could truly work for the ideals of peace and justice.\\

This animated {{adventure series}} is Creator/CartoonNetwork's update of ''WesternAnimation/SuperFriends'', with seven core heroes: {{Franchise/Superman}}, Franchise/WonderWoman, {{Franchise/Batman}}, Franchise/GreenLantern (John Stewart), Franchise/TheFlash (Wally West), [[ComicBook/{{Hawkman}} Hawkgirl]] and the ComicBook/MartianManhunter. Existing in [[Franchise/DCAnimatedUniverse the same universe]] as ''WesternAnimation/BatmanTheAnimatedSeries'', ''WesternAnimation/SupermanTheAnimatedSeries'', ''WesternAnimation/StaticShock'' (post retcon), ''WesternAnimation/BatmanBeyond'', and ''WesternAnimation/TheZetaProject'', this show continued several story threads from those series and introduced new characters who had not previously appeared.

''[[http://www.youtube.com/watch?v=MXph0arElKs Justice League]]'' (Seasons One and Two)

Banding together for the first time to face powerful alien conquerors, Superman, Batman, Wonder Woman, The Flash, the Green Lantern John Stewart, Hawkgirl, and the Martian Manhunter officially organize themselves as a team, anticipating having to deal with other threats that they cannot face alone. This incarnation lasted two seasons and 52 episodes (most of which were two-parters, with three three-parters and a single standalone episode). To avoid overcrowding that would come with featuring [[MandatoryLine every member in every episode]], between two and five members would be in the focal point of a story and the entire League appeared only a few times. Turning most stories into two or three part episodes allowed for a much larger scope that could not be accomplished in 22 minutes.

''[[https://www.youtube.com/watch?v=Sa2jYn3LmlE Justice League Unlimited]]'' (Seasons Three, Four and Five)

The successor series, ''Justice League Unlimited'', [[HeroesUnlimited added more heroes from DC Comics]], many of whom had never before been animated. After the events of the second season, the League recruit heroes from around the world to be prepared for the most powerful threats. Instead of the two or three part episodes, this series returned to the single episode format, which allowed for more obscure heroes and minor comic arcs to be spotlighted. To balance this out, a very strong {{myth arc}} was formed telling of a {{government conspiracy}} against the League, picking up from a few previous episodes, not just from the first ''Justice League'' series, but all the way back from ''WesternAnimation/SupermanTheAnimatedSeries''. In addition, the villains get desperate as they have to face against a very powerful and well organized Justice League and eventually create the LegionOfDoom in response. This incarnation lasted 39 episodes.

Both iterations of ''Justice League'' were distinctive among superhero series for being true ensemble pieces. Pick any member of the core cast and in any given episode he or she might be the main hero of the story, used mainly as part of the larger team, or never even mentioned at all. Supporting cast members rotated out weekly, especially in ''Unlimited''. In addition, while Creator/JackKirby's [[ComicBook/NewGods Fourth World]] creations were used extensively in ''Superman: The Animated Series'', Creator/SteveDitko's creations got the same treatment in this incarnation.

To date, the series comprises the last installments of the ''Franchise/DCAnimatedUniverse''.

There have been a series of animated movies featuring the Justice League in the WesternAnimation/DCUniverseAnimatedOriginalMovies series, separate from the DCAU but which often use the same voice actors from this show. These films include:
[[folder: Justice League Animated Movies]]
* ''WesternAnimation/JusticeLeagueCrisisOnTwoEarths'': Notable for having started off as a movie [[TheMovie bridging the gap]] between the end of ''Justice League'' and the beginning of ''Unlimited''. While no longer set within the [=DCAU=], the film retains many of the plot points and themes of the series.
* ''WesternAnimation/JusticeLeagueDoom'': A loose adaptation of the "Tower of Babel" arc, almost all roles are [[RoleReprisal reprised by the animated series actors]]. [[note]]Michael Rosenbaum plays The Flash again, but unlike the DCAU featuring Wally West, The Flash here is Barry Allen. Additionally, Superman is voiced by his original DCAU voice actor, Tim Daly, as opposed to George Newbern. Hal Jordan is voiced by Nathan Fillion, reprising his role from a previous animated DC film, as opposed to his Firefly co-star Adam Baldwin, who provided Hal's voice for his cameo in the DCAU.[[/note]]
* ''WesternAnimation/JusticeLeagueTheNewFrontier'': A direct adaptation of the famed comic book ComicBook/DCTheNewFrontier, it has a scope larger than just the League and more the general DC universe, renamed to include the Justice League in the title.
* ''WesternAnimation/JusticeLeagueTheFlashpointParadox'': An adaptation of ComicBook/{{Flashpoint}}, it's still a Flash-centric but the League (or lack thereof in the changed timeline) plays a central story.
* ''WesternAnimation/JusticeLeagueWar'': An adaptation of the New 52 version of the origin of the Justice League, as they band together to face an invasion of Earth via ComicBook/{{Darkseid}}. Loosely a sequel to ''The Flashpoint Paradox''.
* ''WesternAnimation/JusticeLeagueThroneOfAtlantis'': A direct sequel to ''Justice League War''. After previously leaving Aquaman out of the origin story, he shows up and joins the League to thwart a plot against the surface by Orm the Ocean Master.
* ''WesternAnimation/JusticeLeagueVsTeenTitans'': In the same continuity as ''War'' and ''Throne of Atlantis'' as well as a series of Batman animated movies. The two super hero teams come to blows concerning ComicBook/{{Raven}} and her connection to her demonic father Trigon.
