Varazdat was the king of Arsacid Armenia from 374/375 until 378. He was installed on the throne by the Roman emperor Valens after the assassination of his kinsman King Pap.

Pap was king of Armenia from 370 until 374/375, and a member of the Arsacid dynasty. His reign saw a short, but notable period of stabilization after years of political turmoil. Although Armenia had been conquered and devastated by the Sassanid king Shapur II in 367/368, Pap was restored to the throne at a young age with Roman assistance in 370. Early in his reign, Armenia and Rome won a joint victory over the Persians at the Battle of Bagavan, and some former territories of the kingdom were reconquered by the efforts of his sparapet (general-in-chief) Mushegh Mamikonian. Although Pap's reign began with a reconciliation of the monarchy, nobility and church, his relations with the church soon deteriorated. Pap allegedly had the Patriarch of Armenia, Nerses I, poisoned, although some later historians doubt this narrative. Pap also eventually ran afoul of the Romans, who suspected him of colluding with the Persians. The emperor Valens unsuccessfully attempted to assassinate him in 373/374, but ultimately succeeded in having him killed in 374/375. He was succeeded by his nephew Varazdat as king.
