Green Lantern: Emerald Knights is a 2011 American animated superhero film that tells various stories featuring members of Green Lantern Corps, including Abin Sur, Laira, Kilowog, and Mogo. It was released on June 7, 2011. While not a direct sequel to First Flight, the film uses the same character designs and includes a cameo by Ch'p, who had a speaking role in the previous film.

It is the eleventh film released under the DC Universe Animated Original Movies banner. It is also the second DC Animated Movie following Batman: Gotham Knight to feature an anthology format, though unlike the latter, it features a single, uniform animation and visual style and an overall linking story. Animation was outsourced to Studio 4°C, JM Animation and Studio Pierrot. The film received mixed-to-positive reviews with many critics praising the animation, voice acting, and action sequences, but criticizing the story and characterization.

Two of the stories ("Mogo Doesn't Socialize" and "Abin Sur") were based on comic stories written by Alan Moore, who has a standing policy of not allowing his name to be used in the credits when his stories are adapted to other media. Although it uses the same name, it has no relation with the 1998 comic book Emerald Knights.

Despite the film featuring a standalone story, Nathan Fillion would later reprise the Green Lantern role in several DC films, particularly the DC Animated Movie Universe.
