Final Fantasy III is the third installment in the Final Fantasy series, developed by Square Co., Ltd., and released on the Nintendo Family Computer (Famicom). It was never released outside Japan until recently for the Nintendo DS.

Up until 2006, it was the only installment in the series to have never seen official English localization, and the only main 2D Final Fantasy game to not see a port or remake. There had been an earlier plan to remake the game for Bandai’s WonderSwan Color handheld (as had been done with the first two installments and the fourth game), but the developers faced difficulties converting the original Famicom version’s cartridge size to the WonderSwan Color, leading to several delays and eventually cancellation after the premature death of the platform. However, an enhanced remake for the Nintendo DS handheld system was released in 2006 in Japan and the U.S., and subsequently released in other parts of the world in 2007. The DS remake of Final Fantasy III is the first iteration of the game to be released internationally.

Final Fantasy III was scored by Nobuo Uematsu, and it is Uematsu’s twenty-first video game music composition.
