Priapatius (also spelled Phriapatius or Phriapites; Parthian: 𐭐𐭓𐭉𐭐𐭕 Friyapat), was the Arsacid king of Parthia from 191 BC to 176 BC. He was the first-cousin-once-removed and successor of Arsaces II (r. 217 – 191 BC). Like many Arsacid monarchs, his reign is sparsely known. His coinage indicates that he managed to rid himself of the influence of the Seleucid Empire. He was succeeded by his son Phraates I.
