Belshazzar (//; Hebrew: בֵּלְשַׁאצַּר, Belshatsar, Greek: Βαλτάζαρ, Baltázar, from Akkadian: 𒂗𒈗𒋀, Bēl-šar-uṣur, meaning "Bel protect the king") was the eldest son of Nabonidus, the last king of the Neo-Babylonian empire, and regent for his father during the latter's prolonged absence from the city, although he never assumed the titles or ritual functions of kingship. He may have been killed when Babylon fell to the Persians in 539 BCE.
Belshazzar also appears as a central character in the story of Belshazzar's feast in the Book of Daniel, recognized by scholars as a work of historical fiction. Daniel's Belshazzar is not malevolent (he rewards Daniel for his interpretation of the writing), but in later Jewish tradition he is presented as a tyrant who oppresses the Jewish people.
