Hiyya b. Joseph
R. Hiyya b. Joseph (or Rav Hiyya b. Yosef;Hebrew: רבי חייא בר יוסף) was an Amora sage of Babylon of the second generation (3rd-century) of the Amoraic era. He studied under the most prominent sages of the Amoraim, R. Abba Arika ("Rav"), and Samuel of Nehardea, and later made Aliyah to the Land of Israel and studied under R. Yochanan bar Nafcha and Shimon ben Lakish.
Teachers and colleagues
He mainly studied under Abba Arika and frequently submits his papers. He would sometimes go to Samul's school and submit second hand reports of Abba Arika, and get Samuel's response. He was also a pupil of Samuel (probably after the death of Abba Arika, like some other of Abba Arika's students), and addressed him with questions, and would some times dispute him 
Upon arrival to the Land of Israel he studied with R. Yochanan bar Nafcha and Shimon ben Lakish, and had submitted rulings of Abba Arika. Even with Yochanan bar Nafcha he disputed on various matters. The Talmud also mentions that Hiyya b. Joseph is addressing Yochanan bar Nafcha with questions, however, he was probably not accounted as his pupil: in a dispute among them, Hiyya b. Joseph is mentioned first, and various doubts on Halachaic matters were brought before both of them as one. At times, Hiyya b. Joseph also delivers statements in the name of Hoshaiah Rabbah.
R. Gidal has studied under him when he was still in Babylon, and delivers statements in his name that are second hand statements made by Abba Arika.
While living in the Land of Israel, he studied under R. Hiyya bar Abba, who was primarily a student of R. Yochanan bar Nafcha. The Rabbis of Caesarea, the students of Caesarea academy, are also citing in his name.
When he was living in the Land of Israel, he made his livelihood from salt trading.
Little is known about his family, except that after immigrating to the Land of Israel alone, He sent someone to bring his wife.
