Rav Ena (Hebrew: רב עינא) was a Jewish Savora sage of the second generation of the Savora era (c. 5th–6th century CE). He served as the head of the Sura Academy (one of the two major Talmudic academies in Babylonia) and was a contemporary counterpart of R. Simuna, who headed the Yeshiva in Pumbedita.
According to the Iggeret Rav Sherira Gaon (an important 10th-century historical epistle by the Gaon of Pumbedita), Rav Ena and R. Simuna were responsible for adding anonymous annotations to the Babylonian Talmud during the process of the Savora arrangement of the Talmud. These additions included further clarifications and halakhic (legal) rulings that were incorporated into the Talmudic text.
Some scholars identify Rav Ena with another figure known as Rav Giza (רב גיזא).
He is recorded as having died in approximately 540 CE (שנת ד'ש' according to the Hebrew calendar).
Rav Ena appears across many tractates of the Talmud, raising questions and citing Scripture in both halakhic (legal) and aggadic (narrative/exegetical) discussions.
