(1134–1194) was count of Toulouse
from 1148 until his death in 1194.
He was the son of Alphonse-Jordan. When Alphonse died in the Holy Land in 1148, the county of Toulouse passed to his son Raymond, at the time 14 years old.
Raymond was implicated in the Cathar crisis. In 1176, Guilhem, the Bishop of Albi organized the council of Lombers, attended by both clerics and princes, including Raymond of Trencavel, Raymond V, and his wife Constance, and the representatives of the Cathars. The crisis later led to the Albigensian Crusade.
In 1154, Raymond married Constance of France, daughter of king Louis VI of France
and his second wife Adélaide de Maurienne
. Constance was the widow
of Eustace IV of Boulogne
. Because Raymond was related to her within prohibited degrees, they were separated by ecclesiastical authority in 1165. They had five children:
- Raymond VI, who succeeded his father
- Aubri, died 1180
- Adelaide or Azalais of Toulouse, who married Roger II Trencavel in 1171 and died in 1199
- Baldwin, born 1165, executed on the orders of Raymond VI in 1214
- Laura died 1230 married Odo of Comminger d.1215
His second wife was Richeza of Poland, widow of Ramon Berenguer II, Count of Provence.
