Thierry IV or Theoderic IV (c. 720 – c. 782) was a Frankish noble. Count of Autun and Toulouse; he was thought to be a son of Sigebert V and grandson of Sigebert IV of Raze. It is now well documented that it supposed Davidic blood was a hoax (see Priory of Sion). Thierry married Auda daughter of Charles Martel sister of Pepin III.
