Dimitri Gutas (Greek: Δημήτρης Γούτας; born 1945, Cairo) is an American Arabist and Hellenist and professor emeritus of Arabic and Islamic Studies in the Department of Near Eastern Languages and Civilizations at Yale University.
Gutas studied classical philology, religion, history, Arabic and Islamic studies at Yale University, where he received his doctorate in 1974.
His main research interests are the classical Arabic and the intellectual tradition of the Middle Ages in the Islamic culture, especially Avicenna, and the Graeco-Arabica, which is the reception and the tradition of Greek works on medicine, science and philosophy in the Arab-Islamic world (especially from the 8th to the 10th century in Baghdad ). In this field he is considered one of the leading experts. He is a co-editor in Yale's Project Theophrastus. He worked with Professor Gerhard Endress of Ruhr University Bochum in Germany to create the Greek and Arabic Lexicon.
Gutas is a member of the advisory board of numerous journals, including the leading journal Arabic Sciences and Philosophy (Cambridge University Press) and co-editor and contributors to the revision of the Ueberweg, a comprehensive history of philosophy.
