The Battle of Clausen was fought on 20 October 1735 near the town of Klausen, which was then in the Electorate of Trier and part of the Holy Roman Empire, and is now in the German state of Rhineland-Palatinate. French forces under the command of Marshal François de Franquetot de Coigny were defeated in an attempt to dislodge imperial troops under the command of Friedrich Heinrich von Seckendorff. The battle was one of the last significant engagements between the combatants in the War of the Polish Succession.
