Final Fantasy II (ファイナルファンタジーII, Fainaru Fantajī Tsū^?) is a console role-playing game developed and published by Square (now Square Enix) in 1988 for the Nintendo Family Computer (Famicom, known internationally as the Nintendo Entertainment System) as a part of the Final Fantasy video game series. The game was only released on this system in Japan; enhanced remakes for the PlayStation (Final Fantasy Origins) and Game Boy Advance (Final Fantasy I & II: Dawn of Souls) were released in North America and the PAL region. Other remakes were released on the WonderSwan Color and mobile phones. The most recent remake (2007) was for the Playstation Portable.

The game's story centers on four youths whose parents were killed during an army invasion. The invasion leader, an emperor, pursues world control using monsters and demons. The youths join a resistance to end the emperor's war.

Final Fantasy II introduced many elements that would later become staples of the Final Fantasy franchise, including chocobos and a character by the name of Cid. It also eliminated the traditional experience-based advancement system, introducing a system wherein the statistics of playable characters increase according to how they are used or acquired.
