G.I. Joe: A Real American Hero is a military-themed line of action figures and toys in Hasbro's G.I. Joe franchise. The toyline lasted from 1982 to 1994, producing well over 500 figures and 250 vehicles and playsets. The line reappeared in 1997 and has continued in one form or another to the present day. It was supported by two animated series as well as a major comic series published by Marvel Comics.

An action figure is a poseable character model figure made most commonly of plastic, and often based upon characters from a film, comic book, military, video game or television program; fictional or historical. These figures are usually marketed toward boys and adult collectors. The term was coined by Hasbro in 1964 to market G.I. Joe to boys.
