Ambalal Dahyabhai Patel, better known as A.D. Patel (13 March 1905 – 1 October 1969), was an Indo-Fijian politician, farmers' leader and founder and leader of the National Federation Party. Patel was uncompromisingly committed to a vision of an independent Fiji, with full racial integration. He was one of the first to advocate a republic, an ideal not realized in his lifetime. He also advocated a common voters' roll and opposed the communal franchise that characterized Fijian politics.
