Gotarzes I of Parthia ruled parts of the Parthian Empire c. 95–90 BC. He was the grandson of Phriapatius and came to power during the troubled times around the end of the reign of Mithridates II. He is mentioned on some astronomical tablets from Babylon and appears to have reigned for some time in Babylonia.
