André Dupont-Sommer (23 December 1900, Marnes-la-Coquette – 14 May 1983, Paris) was a French semitologist.
He specialized in the history of Judaism around the beginning of the Common Era, and especially the Dead Sea Scrolls.
Dupont-Sommer became interested in the Dead Sea scrolls not long after they were discovered.
Writing in French he soon published an overview of the scrolls, Aperçus préliminaires sur les manuscrits de la Mer Morte, which was translated into English in 1952 as The Dead-Sea Scrolls: A Preliminary Survey by Margaret Rowley.
Although his ideas about Christianity were not taken up by the scholarly community, his writings contributed to a better understanding of the scrolls.
