Labashi-Marduk, Chaldean king of Babylon (556 BC), and son of Neriglissar. Labashi-Marduk succeeded his father when still only a boy, after the latter's four-year reign. Most likely due to his very young age, he was unfit to rule, and was murdered in a conspiracy only nine months after his inauguration. Nabonidus was consequently chosen as the new king.
