Guilhem Ademar (Old Occitan [ɡiˈʎɛm adeˈmaɾ]; also spelled Guillem, Adamar, or Azemar; fl. 1190/1195–1217) was a troubadour from the Gévaudan in France. He travelled between the courts of Albi, Toulouse, Narbonne, and Spain. He achieved fame enough during his life to be satirised by the nobleman and monk, Monge de Montaudon. Guilhem entered holy orders towards the end of his life. Sixteen poems—fourteen cansos, a sirventes, and a partimen with Eble d'Ussel—form his surviving corpus. His cansos are his most famous pieces. Usually humorous, several mock the poetry of Ademar's more illustrious contemporary Arnaut Daniel. One canso survives with a tune.
