Ermengarde (Ermengard, Irmgard) was Duchess of Limburg. Her parents were Judith of Kleve and Waleran IV, Duke of Limburg. She was named after her paternal grandmother.
It is possible she was the only child of her parents, but is also equally possible she had a younger sister Sophia.
Ermengarde married count Reginald I of Guelders, but they were childless. Ermengarde died in 1283.
