Yolanda (French: Yolande de Hainault; 1175 – August 1219), often called Yolanda of Flanders, was Empress of the Latin Empire in Constantinople, first as the wife of Emperor Peter from 1216 to 1217 and thereafter as regent until her death in 1219. Peter was captured and imprisoned before he could reach Constantinople, so Yolanda assumed the duties of governing the Empire. She was ruling Marchioness of Namur from 1212 until 1217.
