Abdulrahman al-Ansary (Arabic: عبدالرحمن بن محمد الطيب الأنصاري; 10 October 1935 – 6 March 2023) was a Saudi Arabian archaeologist and professor of archeology at King Saud University, and also member of the first and second terms of the Consultative Assembly of Saudi Arabia.

During his doctoral studies, he focused on the comparative study of Lihynite personal names and trained at archeological excavations with his thesis supervisor at Durham University and Motya, Sicily,[3] and with Professor Kathleen Kenyon in Jerusalem in 1966.

[4] Al-Ansary was a faculty member of King Saud University (formerly Riyadh University) from 1966 to 1999 where he held several positions and roles[5] including dean of the College of Arts (1971–1972 and 1988–1994),[6] chairman of the Department of History (1974–1978) and chairman of the Department of Archeology and Museology (1978–1986).

[7] Professor al-Ansary is perhaps most known for leading the archeological excavation in the city of Qaryat al-Fau between 1972 and 1995 while at King Saud University.

[5] In 1982 he authored a book entitled "Qaryat al-Fau: A Portrait of Pre-Islamic Civilisation in Saudi Arabia",[1] which presented the results of the first six seasons of excavation.
