Trương Định, sometimes known as Trương Công Định, was a mandarin (scholar-official) in the Nguyễn dynasty of Vietnam under Emperor Tự Đức. He is best known for leading a guerrilla army in southern Vietnam against French forces in defiance of the emperor. He refused to recognise the 1862 Treaty of Saigon that ceded Vietnamese territory to France.
