Sultan Bashiruddin Mahmood (Urdu: سلطان بشیر الدین محمود; b. 1940) is a Pakistani nuclear engineer and a scholar of Islamic studies.
Having spent a distinguished career in the Pakistan Atomic Energy Commission (PAEC), he founded the Ummah Tameer-e-Nau (UTN) in 1999 – a right-wing organisation that was banned and sanctioned by the United States in 2001. He was the subject of a criminal investigation launched by the Federal Investigation Agency (FIA) over unauthorized travel in Afghanistan prior to the September 11 attacks in 2001. Mahmood was among those who were listed and sanctioned by the Al-Qaida Sanctions Committee in December 2001. He was also sanctioned as a Specially Designated Global Terrorist by the United States' Office of Foreign Assets Control, with an address lisiting of the Al-Qaeda Wazir Akbar Khan safe house, Kabul.
He has since been living in anonymity in Islamabad, authoring books on the relationship between Islam and science.
