Charles de Louviers, sieur de Maurevert (; - 14 April 1583) was a French noble and assassin during the French Wars of Religion, whose failed assassination of Admiral Coligny led to the Massacre of Saint Bartholomew. Maurevert was from a prominent Champagne family in a region that was increasingly torn apart by intra-family conflict. He served as a page for the Guise family in his youth before committing a murder that forced him to go on the run. By 1569 he had converted to Protestantism and was serving under the seigneur de Mouy in their rebel army. Deciding to kill his commanding officer, he took the body over to the Catholic camp and was rewarded with money and a knighthood.
