Ermesinde of Luxembourg (1186 – 12 February 1247) also known as Ermesinde of Namur was the Countess of Luxembourg Laroche and Durbuy between 1197 and 1247. She was the only child of Henry IV Count of Luxembourg and Namur and his second wife Agnes of Guelders.Prior to her birth her aging father Henry IV had designated Baldwin V Count of Hainaut as his likely successor. However when Ermesinde was born in 1186 and Henry IV named her as his heir a war of succession inevitably took place.
