G.I. Joe is an American media franchise and a line of action figures owned and produced by the toy company Hasbro. The initial product offering represented four of the branches of the U.S. armed forces with the Action Soldier, Action Sailor, Action Pilot, Action Marine and later on, the Action Nurse. The name is derived from the usage of "G.I. Joe" for the generic U.S. soldier, itself derived from the more general term "G.I.". The development of G.I. Joe led to the coining of the term "action figure". G.I. Joe's appeal to children has made it an American icon among toys.

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.
