Kurt Busiek is an American comic book writer notable for his work on the Marvels limited series, his own title Astro City, and his four-year run on Avengers.

Busiek did not read comics as a youngster, as his parents disapproved of them. He began to read them regularly around the age of 14, when he picked up a copy of Daredevil #120. This was the first part of a continuity-heavy four-part story arc; Busiek was drawn to the copious history and cross-connections with other series. Throughout high school and college, he and future writer Scott McCloud practiced making comics. During this time, Busiek also had many letters published in comic book letter columns, and originated the theory that the Phoenix was a separate being who had impersonated Jean Grey, and that therefore Grey had not died—a premise which made its way from freelancer to freelancer, and which was eventually used in the comics.

During the last semester of his senior year, Busiek submitted some sample scripts to editor Dick Giordano at DC Comics. None of them sold, but they did get him invitations to pitch other material to DC editors, which led to his first professional work, a back-up story in Green Lantern #162 (Mar. 1983).

Busiek has worked on a number of different titles in his career, including Arrowsmith, The Avengers, Icon, Iron Man, The Liberty Project, Ninjak, The Power Company, Red Tornado, Shockrockets, Superman: Secret Identity, Thunderbolts, Untold Tales of Spider-Man, JLA, and the award-winning Marvels and the Homage Comics title Kurt Busieks Astro City.

In 1997, Busiek began a stint as writer of Avengers alongside artist George Pérez. Pérez departed from the series in 2000, but Busiek continued as writer for two more years, collaborating with artists Alan Davis, Kieron Dwyer and others. Busieks tenure culminated with the Kang Dynasty storyline. In 2003, Busiek re-teamed with Perez to create the JLA/Avengers limited series.
