The All-Star Squadron is a DC Comics superhero team that debuted in Justice League of America #193 and was created by Roy Thomas, Rich Buckler and Jerry Ordway. Although the team was introduced in the 1980s, its self-titled series took place in the 1940s, retroactively inserting their narratives into the fictional history of the DC Comics superheroes. The team included many of DC's Golden Age era characters, new characters, and other World War II superheroes that DC did not own during the 1940s but later acquired. The name "All-Star Squadron" was creator Roy Thomas' reference to All Star Comics, the series that introduced the Justice Society of America, the first comic book superhero team.

Roy William Thomas Jr. is an American comic book writer and editor. He was Stan Lee's first successor as editor-in-chief of Marvel Comics and possibly best known for introducing the pulp magazine hero Conan the Barbarian to American comics. Thomas is also known for his championing of Golden Age comic-book heroes – particularly the 1940s superhero team the Justice Society of America – and for lengthy writing stints on Marvel's X-Men and The Avengers, and DC Comics' All-Star Squadron, among other titles.
