BĀZRANGĪ (also known as Bazrangids or Badhrangids) is the attested family name of a dynasty of petty rulers in south western Iran near the end of Arsacid Empire as well as the name of geographical districts.

The lord Sasan who is named as the eponymous ancestor of the Sasanians took, according to Tabari, a wife from a family called "Bazrangi". The woman was called Rāmbehešt and according to Tabari "possessed beauty and perfection". She bore Sasan a son called Papg.

In the account of Tabari, Ardashir, the founder of Sassanid dynasty was sent for educational reasons, at the request of his father Papg, to Tīrī who was the eunuch of Gōčehr the king of Eṣṭaḵr. Later Ardashir succeeded Tīrī who was the chief officer (i.e. argbed) of Dārābgerd. Ardashir managed to make a number of local conquests and then wrote to his father to revolt against Gōčehr. Papg did so and killed Gōčehr and took his throne. This is the last time Tabari mentions about Gōčehr or the Bāzrangī family and other notices of Bāzrangī in later sources are all taken from Ṭabarī. There has not been found any coins naming Gōčehr or Bāzrangī.
