Dadhburzmihr (also spelled Dadmihr or Dazmihr) was the independent ruler (ispahbadh) of Tabaristan. He succeeded his father Farrukhan the Great in 728 and reigned until his death in 740/1. According to the 13-century Iranian historian Ibn Isfandiyar, Dadhburzmihr enjoyed a peaceful reign, facing no invasions from the Arab Caliphate, due to their attention being directed towards local revolts. His 6 year old son, Khurshid succeeded him.
