William VIII (in Occitan: Guilhem; died 1202) was Lord of Montpellier, the son of William VII and Matilda of Burgundy.

William VIII married Eudokia Komnene, grand-niece of the Byzantine emperor Manuel I Komnenos.

Lacking a male heir, William separated from Eudokia, sending her to a monastery in Ariane.

[2] William then married Agnes of Castile and sired eight more children: The Pope ruled William's marriage to Agnes as illegitimate and Marie was given the throne.
