Abdulla al-Hadj (Arabic: عبد الله الحاج; died 1843) was an English pirate primarily known for his activity in the South China Sea. Abdulla was born in England but was taken to Arabia while he was still young. While in Arabia, he converted to Islam and eventually found his way to Murdu where he found a job as the rajah's chief advisor. Abdulla was most known for his capture of a British trading vessel that was stopped at Murdu in northern Borneo. While the ship was taking on cargo, Abdulla and a partner boarded the ship and killed the captain and another officer, took over the ship and stripped it bare. The rajah of Murdu, hoping to avoid punishment turned Abdulla over to the Honourable East India Company while keeping the loot for himself. After a trial, Abdulla was imprisoned for life in Bombay.
