Laconicus (Greek: Λακωνικός; reigned in 192 BC) was the last known king of Sparta. Laconicus was appointed as a king after the murder of Nabis. He was a boy, possibly of royal descent, who had been raised with Nabis' own sons. After the Achaean general Philopoemen captured the city in 192 BC Sparta was forced to join the Achaean League and the position of king was abolished. After Laconicus was deposed his fate is unknown.
