Dr. Henry "Hank" Pym is a fictional character, a superhero that appears in publications by Marvel Comics. Created by editor and plotter Stan Lee, scripter Larry Lieber and penciler Jack Kirby , the character first appeared in Tales to Astonish #27 (Jan. 1962).

Pym's character, which debuted in a standalone science-fiction anthology story, returned several issues later as the superhero Ant-Man, with the power to shrink to the size of an insect. Pym is eventually given a crime-fighting partner, Janet van Dyne, the Wasp, and goes on to assume other superhero identities, including the size-changing Giant-Man and Goliath; the insect-themed Yellowjacket; and, as of 2009, the Wasp.

Debuting in the Silver Age of Comic Books, the character of Henry Pym has featured in other Marvel-endorsed products such as animated films; arcade and video game; television series and merchandise such as action figures and trading cards.

Henry Pym debuted in a seven-page solo cover story titled "The Man in the Ant Hill" (about a character who tests shrink technology on himself) in the science fiction/fantasy anthology Tales to Astonish #27 (Jan. 1962). The creative team was editor-plotter Stan Lee, scripter Larry Lieber, penciler Jack Kirby, and inker Dick Ayers, with Lee stating in 2008: "I did one comic book called 'The Man in the Ant Hill' about a guy who shrunk down and there were ants or bees chasing him. That sold so well that I thought making him into a superhero might be fun".
