Yolanda of Hainault (French: Yolande de Hainault; 1175 – September 1219), often called Yolanda of Flanders, was Empress of the Latin Empire in Constantinople from 1217 to 1219. Her husband Peter was captured and imprisoned before he could reach Constantinople, so Yolanda ruled the Empire alone. She was ruling Marchioness of Namur from 1212 until 1217.
