Orodes I (also spelled Urud I; Parthian: 𐭅𐭓𐭅𐭃 Wērōd/Urūd), was king of the Parthian Empire from 80 to 75 BC. He was the son and heir of Gotarzes I (r. 91–87/80 BC). His reign is relatively obscure. His throne may have been usurped in 87–80 BC by his supposed uncle Mithridates III, however, this has found little support in scholarship. Of his military activities, it is known that Orodes I re-established Parthian rule in Elymais in 78 BC, which had been independent since 81/80 BC. Orodes I later lost the throne to the aged Parthian prince Sinatruces, who belonged to a different branch of the royal Arsacid family.
