The Babylonian court name assigned to Hananiah, one of the four Judean youths deported to Babylon and trained in Chaldean learning (Dan 1:7). Shadrach appears alongside Meshach and Abed-nego throughout Daniel 3, where the three refuse to worship Nebuchadnezzar's golden image and are cast into a fiery furnace — only to emerge unharmed, prompting the king's decree honoring their God. Daniel 2:49 notes that Shadrach was appointed over the affairs of the province of Babylon at Daniel's request. The name's etymology remains debated; some connect it to Shudur-Aku ('command of Aku,' a moon deity), though this is uncertain. French 'Schadrac' and German 'Schadrach' preserve the Aramaic form closely.
