The Hebrew University of Jerusalem (HUJI; Hebrew: הַאוּנִיבֶרְסִיטָה הַעִבְרִית בִּירוּשָׁלַיִם) is an Israeli public research university based in Jerusalem. Co-founded by Albert Einstein and Chaim Weizmann in July 1918, it is the second-oldest institution of higher learning in Israel, having been founded 30 years before the establishment of the State of Israel but six years after the older Technion university.
The university has five affiliated teaching hospitals (including the Hadassah Medical Center), seven faculties, more than 100 research centers, and 315 academic departments. As of 2018, one-third of all the doctoral candidates in Israel were studying at the HUJI. The HUJI has three campuses in Jerusalem: one in Rehovot, one in Rishon LeZion and one in Eilat. Until 2023, the world's largest library for Jewish studies—the National Library of Israel—was located on its Edmond J. Safra campus in the Givat Ram neighbourhood of Jerusalem.
