Hillel II (Hebrew: הלל נשיאה, Hillel the Nasi), also known simply as Hillel, was an amora of the fifth generation in the Land of Israel. He held the office of Nasi of the Sanhedrin between 320 and 385 CE. He was the son and successor of Judah III. He is sometimes confused with Hillel the Elder, as the Talmud sometimes simply uses the name "Hillel".
