Judah II or Nesi'ah I was a Jewish sage who lived in Tiberias in the Land of Israel, in the middle of the third century CE. He is mentioned in the classical works of Judaism's Oral Torah, the Mishnah and Talmud. There he is variously called "Judah," "Judah Nesi'ah" (= "ha-Nasi"), and occasionally "Rabbi" like his grandfather, Judah haNasi. As Judah III is also designated as "Judah Nesi'ah," it is often difficult, sometimes impossible, to determine which one of these patriarchs is referred to.
