Sir John Bagot Glubb (16 April 1897 – 17 March 1986), known as Glubb Pasha and nicknamed Abu Hanik, was a British officer known for his command of the Arab Legion between 1939 and 1956.

Glubb Pasha served in France during World War I, then was transferred to Iraq in 1920, when Iraq was under British mandate at the time. In Iraq, he worked to build relations with the tribes up to the borders of the Al Saud and played an important role in shaping British-Arab relations in that region.

He studied at Cheltenham College, and became an officer in the Arab Legion in 1930. The following year, he founded the Badia Forces, a force composed exclusively of Bedouins, to control the crisis that had struck the south of the country. Within a few years, he was able to stop the mutual invasions between the Bedouin tribes, and the crisis quickly became a thing of history. In 1939, Glubb succeeded Frederick Gerard Beck as commander of the Jordanian Arab Legion, during which time he transformed the army into the best-trained force in the Arab region. He remained in command of the Jordanian Arab Legion until March 2, 1956, when King Hussein bin Talal, in coordination with the Jordanian Free Officers Movement, relieved him of his duties in his decision to Arabize the leadership of the historic Arab Legion. This decision came as a shock to the British Empire and led to the deterioration of Jordanian relations with Britain, America, and their allies.
