Johanan (Hebrew: יוֹחָנָן, romanized: Yoḥānān), son of Joiada, was the fifth High Priest of the Temple in Jerusalem after it was rebuilt after the end of the Babylonian captivity.
Josephus records that Johanan's brother Joshua was promised the high priesthood by Bagoas, general of Artaxerxes.
His son Jaddua eventually took over the position when Johanan died, as briefly mentioned by Josephus, but was not accepted in the book of chronicles according to Nehemiah 12:23.
[2] It is addressed to Bagoas, governor of Yehuda Medinata, and is a request for the rebuilding of the temple to Yahweh at Elephantine; Egyptians had destroyed the previous one.
On a silver coin from the late Achaemenid Empire, Dan Barag and other scholars have identified the Hebrew phrase יחנן הכהן ("Yoḥānān the priest").
She believes that the coin refers to the same individual as the one mentioned in Josephus and Nehemiah, and that it is unnecessary to propose a second Johanan.
