Palestinian amora of priestly descent; flourished at the end of the third century. In the Palestinian Talmud he is also called Ḥiyya bar Ba or Ḥiyya bar Wa (; Yer. Ber. iii. 6a, iv. 7d); and in both Talmuds he is frequently mentioned merely as R. Ḥiyya, the context showing that Ḥiyya bar Abba is meant. Though a native of Babylon, where, perhaps, for a very short time he came under the influence of Mar Samuel (Weiss, "Dor," iii. 94), he migrated to Palestine at a very early age. There he studied under Ḥanina and Joshua b. Levi, and came into very close contact with Simeon b. Laḳish. He is, moreover, known as a disciple of Johanan, after whose death he and his friends Ammi and Assi were the recognized authorities on the Halakah in Palestine.

Ḥiyya was distinguished for the care with which he noted the sayings of his masters (Ber. 38b), and in questions of doubt as to the phraseology of a tradition the version of Ḥiyya was preferred (Ber. 32b, 38b). Though he was the author of many haggadot, he denounced every attempt to collect and commit them to writing, and upon seeing such a collection he cursed the hand that wrote it (Yer. Shab. xvi. 15c). His interest was centered in Halakah, in the knowledge of which he probably excelled all his Palestinian contemporaries. Together with Ammi and Assi, he formed a court of justice before which a certain woman named Tamar was tried. The sentence involved Ḥiyya and his associates in difficulty, and might have had disastrous results had not Abbahu promptly come to their assistance (Yer. Meg. iii. 74a).

Ḥiyya was very poor, and therefore was compelled to go lecturing from town to town in search of a livelihood; he even temporarily left Palestine (Yer. Ma'as. Sh. v. 56b). He was greatly annoyed that the lecturer on Haggadah drew a larger audience than he (see Jew. Encyc. i. 36, s.v. Abbahu). Through stress of poverty he accepted a commission from Judah II. to collect money to defray the expenses of the decaying patriarchate. The esteem in which Ḥiyya was held is manifested in the credentials obtained for him by Eleazar b. Pedath: "Behold, we have sent you a great man, our envoy. Until his return he possesses all the powers that we do." According to another version the introduction ran: "Behold, we have sent you a great man. His greatness consists in this, that he is not ashamed to say 'I know not' " (Yer. Ḥag. i. 76d; Yer. Ned. x. 42b). At another time Ḥiyya, Ammi, and Assi were appointed by Judah II. to visit the various communities in Palestine, with the view of reawakening interest in the study of the Law (Yer. Ḥag. i. 76c).

Ḥiyya had several brothers: R. Nathan ha-Kohen, also known as R. Kohen (or R. Nathan) b. Abba; Rabbannai, or R. Bannai; and R. Simeon b. Abba. He had several children, among whom were R. Abba, R. Kahanah, and R. Nehemiah.
