Ratan Singh (? – 15 May 1548) was the Rajput ruler of Amber from 1537 to 1548. Reigning during a period of political uncertainty, Ratan Singh proved himself to be an ineffective monarch. He faced multiple rebellions among his relatives during his short reign as well as incursions by the Sur Empire. He was assassinated and supplanted by his brother after ten years of rule.
