Shapur II (Middle Persian: 𐭱𐭧𐭯𐭥𐭧𐭥𐭩 Šābuhr, 309–379), also known as Shapur the Great, was the tenth King of Kings (Shahanshah) of the Sasanian Empire. He took the title at birth and held it until his death at age 70, making him the longest-reigning monarch in Sasanian history. He was the son of Hormizd II (r. 302–309).

His reign saw the military resurgence of the country and the expansion of its territory, which marked the start of the first Sasanian golden era. Thus, along with Shapur I, Kavad I and Khosrow I, he is regarded as one of the most illustrious Sasanian kings. His three direct successors, on the other hand, were less successful. At the age of 16, he launched enormously successful military campaigns against Arab insurrections and tribes.

Shapur II pursued a harsh religious policy. Under his reign, the collection of the Avesta, the sacred texts of Zoroastrianism, was completed, heresy and apostasy were punished, and Christians were persecuted. The latter was a reaction against the Christianization of the Roman Empire by Constantine the Great. At the time of Shapur's death, the Sasanian Empire was stronger than ever, with its enemies to the east pacified and Armenia under Sasanian control.
