Sultan Abdul Hakkul Mubin (also known as Abdul Mubin) was the fourteenth sultan of Brunei, and was involved in the Brunei Civil War. He ruled from 1660 to 1673 after killing Sultan Muhammad Ali, and was killed and succeeded by Muhyiddin.

Abdul Hakkul Mubin was once known as Pengiran (Prince) Abdul Mubin. However, in 1660 his son was killed by the son of the reigning Sultan Muhammad Ali. In revenge he killed Muhammad Ali and took the throne, taking the name Abdul Hakkul Mubin. He tried to appease the previous Sultan's followers by appointing Muhammad Ali's grandson, Muhyiddin, as the new Bendahara ("Chief Minister"). However Muhammad Ali's supporters convinced Muhyiddin to take revenge sparking the Brunei Civil War. Abdul Hakkul Mubin's rule, and the Brunei Civil War, ended with his death and Muhyiddin's victory in 1673.

The earliest historical record of the Sultans of Brunei is not clearly known due to the poor early documentation of Brunei's history. Many elder members of the House of Bolkiah claim that their ancestors were the BaHassan and BaAlawi Saadah from Tarim and Hadhramawt in Yemen. In addition there has been an effort to Islamise the history, with the "official history" not matching up with verifiable foreign sources. The Batu Tarsilah, the genealogical record of the kings of Brunei, was not started until 1807 CE. Therefore, much of the intepretation on history relied on earlier Chinese sources and legends. It seems that the early Sultanate of Brunei was dependent on Chinese support, and perhaps early Sultans were of Chinese origin. Furthermore the earliest Sultans may have been practising the Hindu or Buddhist religions, with early names indicating this origin.
