G.I. Joe: A Real American Hero (also known as Action Force in Finland, Sweden and the UK) 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.

The toyline continues to play a large part in Hasbro's G.I. Joe franchise. This version of G.I. Joe is still much recognized by many people who grew up in the 1980s and 1990s.
