Raymond III (also Ramon or Raimundo and sometimes numbered Raymond II) (died 1008) was the count of Rouergue and Quercy from 961 or 965 to his death. Raymond achieved a suzerainty over neighbouring counties and successfully titled himself marchio (or dux) or margrave of Septimania. He was the son and successor of Raymond II.
By his death, he was suzerain over Albi and Nîmes and his son received 50,000 solidi or one half of the total payment for the archbishopric of Narbonne in 1016. On his death, his son Hugh received Rouergue, but the margraviate passed to William III of Toulouse.
