The Comtessa de Dia (Countess of Die), possibly named Beatritz or Isoarda (fl. c. 1175 or c. 1212), was a trobairitz (female troubadour). She is only known as the comtessa de Dia in contemporary documents, but was most likely the daughter of Count Isoard II of Diá (a town northeast of Montelimar now known as Die in southern France). According to her vida, she was married to William of Poitiers, but was in love with and sang about Raimbaut of Orange (1146-1173). Bruckner, Shepard, and White cite Angela Rieger's analysis of the songs, which associates them, through intertextual evidence, with the circle of poets composed of Raimbaut d'Aurenga, Bernart de Ventadorn, and Azalais de Porcairagues. Marcelle Thiébaux, and Claude Marks have associated her not with Raimbaut d'Aurenga but with his nephew or great nephew of the same name. If her songs are addressed to Raimbaut d'Aurenga's nephew Raimbaut IV, the Comtessa de Dia may have been urging the latter to support Raymond V of Toulouse. It has been hypothesised that the Comtessa de Dia was in fact married to Guillem's son, Ademar de Peiteus, whose wife's name was Philippa de Fay, and that her real lover was Raimbaut de Vaqueiras. Five of the Comtessa's works survive, including 4 cansos and 1 tenson. Scholars have debated whether or not the Comtessa authored , a tenso typically attributed to Raimbaut d'Aurenga. One reason for this is the similarities between this composition and her own . A second reason references the words in her vida, ("And she fell in love with Sir Raimbaut d'Aurenga, and made about him many good cansos"). A tenso between Giraut de Bornelh and Alamanda de Castelnau closely matches the structure of ("I must sing a song I'd rather not"). The phrase in it, ("dressed nor nude") echoes ("in bed and when I am dressed") in ("I dwell in sorrow"). The tenso may have been composed as a response to these songs. Her song in the Occitan language is the only canso by a trobairitz to survive with its music intact. The music to A chantar is found only in Le manuscript di roi, a collection of songs copied around 1270 for Charles of Anjou, the brother of Louis IX. Her extant poems are: Typical subject matter used by Comtessa de Dia in her lyrics includes optimism, praise of herself and her love, as well as betrayal. In ,
