Brunissende of Foix (died September 1324) was Countess of Périgord by marriage to Count Elias VII.
According to several sources, Brunissende had influence in the politics of the newly formed Avignon Papacy due to her close relationship with Pope Clement V. This arrangement supposedly enabled Brunissende to ensure a clerical career for her son, Hélie, who would go on to have an influential career as a cardinal.
Brunissende was the daughter of Roger-Bernard III, Count of Foix by his wife Margaret, Viscountess of Béarn.
[2] Brunissende was rumoured to be the mistress of Clement V, yet Giovanni Villani confessed that stories he had heard of the relationship between her and the Pope were only hearsay.
[4] Her funeral saw one of the many dramatic episodes in the long, futile struggle of the counts of Perigord with the independent townsmen of Perigueux.
