Joseph Kelly is an American comic book writer, penciler and editor who has written such titles as Deadpool, Uncanny X-Men, Action Comics, and JLA, as well as award-winning work on The Amazing Spider-Man and Superman. As part of the comics creator group Man of Action Studios, Kelly is one of the creators of the animated series Ben 10.

JLA was a monthly comic book published by DC Comics from January 1997 to April 2006 featuring the Justice League of America. The series restarted DC's approach to the Justice League, which had initially featured most of the company's top-tier superheroes but shifted in the 1980s to featuring a rotating cast of established characters alongside newer ones and also saw that franchise expand to several spin-off series, diluting the prestige of the name brand. When relaunched by writer Grant Morrison, the team again focused on the most recognizable, powerful, and long-lasting heroes in DC's library.
