Phan Quang Đán (November 6, 1918 – March 26, 2004) was a Vietnamese political opposition figure who was one of only two non-government politicians who won a seat in the 1959 South Vietnamese election for the National Assembly. Subsequently, he was arrested by the forces of President Ngô Đình Diệm and not allowed to take his seat. The most prominent dissident during the rule of Diệm, he is remembered more for his incarceration than his activities after Diệm's fall, when he became a cabinet minister.
