Shapur IV (Middle Persian: 𐭱𐭧𐭯𐭥𐭧𐭥𐭩 Šāhpuhr), was king of Sasanian Armenia from 415 to 420, who briefly ruled the Sasanian Empire in 420. The only witnesses to this brief reign are the 5th century Armenian historians Łazar Pʿarpecʿi and Movses Khorenatsʿi, and the Mandaean Book of Kings, in which he appears as "King Shābur, son of Yazdiger."
