Hugh IX de Lusignan (c. 1163–1219), known as "le Brun" (the Brown), Count of La Marche, was the eldest son of Hugh VIII and the father of Hugh X de Lusignan. He anchors the Poitou continuity in the generation between Hugh VIII (whose captivity in Aleppo pulled the family into the East) and Hugh X (whose marriage to Isabelle d'Angoulême produced Alix and her siblings).
