Business Division 3 (第3ビジネス・ディビジョン, Dai San Bijinesu Dibijon?) was an internal development division within Square Enix. It was formed in 2013 after an internal restructuring, and initially focused on remasters, ports and mobile titles in the Kingdom Hearts series, eventually moving on to developing new mainline titles in said series. In 2019, following another internal restructuring, Business Division 3 was merged with Business Division 1 and Business Division 4 to form Creative Business Unit I.
