Dunash ibn Tamim (Hebrew: דונש אבן תמים‎) was a Jewish tenth century scholar, and a pioneer of scientific study among Arabic-speaking Jews. His Arabic name was أبو سهل Abu Sahl; his surname, according to an isolated statement of Moses ibn Ezra, was "Al-Shafalgi," perhaps after his (unknown) birthplace. Another name referring to him is Adonim. His first name seems to have been native to northern Africa, it was common among medieval Berbers. The younger contemporary of Ibn Tamim, Dunash ben Labrat, for instance, was born in Fez.
