Final Fantasy III (ファイナルファンタジーIII Fainaru Fantajī Surī) is a role-playing video game developed and published by Square in 1990 for the Nintendo Entertainment System as the third installment in the Final Fantasy series. It is the first numbered Final Fantasy game to feature the job-change system.

The story revolves around four orphaned youths drawn to a crystal of light. The crystal grants them some of its power, and instructs them to go forth and restore balance to the world. Not knowing what to make of the crystal's pronouncements, but nonetheless recognizing the importance of its words, the four inform their adoptive families of their mission and set out to explore and bring back balance to the world.

The game was originally released in Japan on April 27, 1990. It had never been released outside of Japan until a remake was released on the Nintendo DS on August 24, 2006. At that time, it was the only Final Fantasy game not previously released in North America or Europe. There had been earlier plans to remake the game for Bandai's WonderSwan Color handheld, as had been done with the first, second, and fourth installments of the series, but the game faced several delays and was eventually canceled after the premature cancellation of the platform. The Nintendo DS version of the game was positively received internationally, selling over one million copies in Japan.

It was also released for the many other systems: the Japanese Virtual Console version (Famicom version) on July 21, 2009 (Wii) and January 8, 2014 (Wii U), an iOS port of the Nintendo DS remake on March 24, 2011, an Android version on March 12, 2012, a PlayStation Portable version on late September 2012 (Downloadable only version outside of Japan via PlayStation Network) and Android-based Ouya console on April 11, 2013.
