Rabbi Chanan HaMitzri was a tanna. He is brought in several tractates of the Talmud for a single, distinctive ruling concerning the offerings: that even when the blood is already in the cup, one may bring a second animal and pair it with the first. This teaching appears in Yoma, Zevachim, Menachot, and Temurah, where it is cited in his name as the source for the principle that he does not hold of dichuy — the idea that an offering once set aside or disqualified is permanently rejected.
Because of this view, the Gemara attaches his name to anonymous teachings that proceed on the same assumption: when a ruling presumes that an animal can still be paired even after the process has begun, the discussion identifies it as following Chanan HaMitzri. The Sages Rav Yosef, Abaye, Rava, and Ravina are all recorded engaging with his position in clarifying these laws.

Hanan the Egyptian was a rabbi of the 2nd century who first lived at Alexandria. He later moved to Judaea and was active among the scholars of Jabneh. He was a disciple of Rabbi Akiva and is quoted among "those who argued before the sages." Only one law, relating to the Temple service on Yom Kippur, is preserved in his name.
