Ḥanan bar Rava or Ḥanan bar Abba was a Talmudic sage and second-generation Babylonian Amora. He lived in Israel, moved to Babylonia with Abba b. Aybo, and died there ca. 290 CE. He is distinct from the late-generation Babylonian Amora of the same name who apparently conversed with Ashi.

Amoraim refers to Jewish scholars of the period from about 200 to 500 CE, who "said" or "told over" the teachings of the Oral Torah. They were primarily located in Babylonia and the Land of Israel. Their legal discussions and debates were eventually codified in the Gemara. The Amoraim followed the Tannaim in the sequence of ancient Jewish scholars. The Tannaim were direct transmitters of uncodified oral tradition; the Amoraim expounded upon and clarified the oral law after its initial codification.
