The Hall of Mirrors () is a grand Baroque style gallery and one of the most emblematic rooms in the royal Palace of Versailles near Paris, France. The grandiose ensemble of the Hall and its adjoining salons was intended to illustrate the power of the absolutist monarch Louis XIV. Located on the first floor ("piano nobile") of the palace's central body, it faces west towards the Palace Gardens. The Hall of Mirrors has been the scene of events of great historic significance, including the Proclamation of the German Empire and the signing of the Treaty of Versailles.
