Judas is the anglicized Greek rendering of the Hebrew name Yehudah (Hebrew: יְהוּדָה), also rendered in English as Judah.

• Judah (Biblical figure), a son of the patriarch Jacob and, according to the Bible, ancestor of the Davidic royal line of ancient Israel.

By Hellenitic times Judah (Heb. Yehudah) had become a common first name among Jews (whose collective name - "Yehudim" יהודים in Hebrew - is also derived from the same source) and, in the English form Judah, has remained so up to the present.
