Judah bar Ezekiel (220–299 CE) (Hebrew: יהודה בן יחזקאל; also known as Rav Yehuda bar Ezekiel), was a Babylonian amora of the 2nd generation. He was the most prominent disciple of Rav (Abba Arika), in whose house he often stayed, and whose son Hiyya was his pupil (Er. 2b). After Rav's death Judah went to Samuel of Nehardea, who esteemed him highly and called him "Shinena" (= "sharpwitted"; Ber. 36a; Kid. 32a) or he with the long teeth (R' Hai Gaon in a responsa). He remained with Samuel until he founded a school of his own at Pumbedita. He died there in 299.
