Abraham Fraenkel (Hebrew: אברהם הלוי (אדולף) פרנקל; 17 February, 1891 – 15 October, 1965) was a German-born Israeli mathematician.

Abraham Adolf Halevi Fraenkel studied mathematics at the Universities of Munich, Berlin, Marburg and Breslau.

Due to the severe housing shortage in post-First World war Germany, for a few years the couple lived with fellow professor Kurt Hensel as subtenants.

He then made the choice of accepting a position at the Hebrew University of Jerusalem, which had been founded four years earlier, where he spent the rest of his career.

Fraenkel was also interested in the history of mathematics, writing in 1920 and 1930 about Gauss's works in algebra, and he published a biography of Georg Cantor.
