Abdul Aziz Umar

Abdul Aziz bin Haji Umar (born 20 March 1936) is a Bruneian aristocrat and politician who held a wide range of positions in the government of Brunei. Before that, he served as the minister of communications, minister of education, and minister of health. Beginning his career in the civil service with his first appointment in 1964, he held various roles until Brunei's independence in 1984, including serving as the acting menteri besar (chief minister) from 1981 to 1983.

Abdul Aziz is recognised as Brunei's first minister of education and its last colonial chief minister. As one of the nation's 'founding leaders,' he was part of a group of Bruneians with Western educations who significantly contributed to the country's development after gaining independence. A leading advocate for adopting Melayu Islam Beraja (MIB) as Brunei's national philosophy, Abdul Aziz played a pivotal role in integrating this concept into the nation's educational system. He also held prominent positions, including chairman of the Brunei Investment Agency (BIA), and was a member of the Royal Succession Council, the Privy Council, and the Brunei Islamic Religious Council (MUIB). Since 15 May 1998, he has served as the vice-chairman of the board of trustees at the Oxford Centre for Islamic Studies, University of Oxford.
