Cambyses II (Old Persian: 𐎣𐎲𐎢𐎪𐎡𐎹, romanized: Kaᵐbūjiya) was the second King of Kings of the Achaemenid Empire, reigning 530 to 522 BCE. He was the son of and successor to Cyrus the Great (r. 550 – 530 BC); his mother was Cassandane. His relatively brief reign was marked by his conquests in North Africa, notably Egypt, which he took by defeating pharaoh Psamtik III (r. 526–525 BC) at the battle of Pelusium in 525 BC. After his victory in Egypt, he expanded the empire's holdings in Africa by taking Cyrenaica, the coastal region of eastern Libya. In the spring of 522 BC, Cambyses had to leave Egypt hastily to put down a revolt in Persia.

En route in Syria (Eber-Nari), Cambyses somehow received a thigh wound; it soon became gangreneous. Cambyses died three weeks later in Agbatana, likely the modern city of Hama. He died childless, and was thus succeeded by his younger brother Bardiya. Bardiya ruled for a short time, and was then overthrown by Darius the Great (r. 522–486 BC), who went on to increase the power of the Achaemenids even further.

Before his accession, Cambyses was governor of northern Babylonia under his father Cyrus from April to December 538 BCE. He held positions in Babylon and Sippar. In 530 BCE his father made him co-ruler. Cyrus then set off on an expedition against the Massagetae of Central Asia, where he met his end. Cambyses thus became the sole ruler of the vast Achaemenid Empire. According to chroniclers, he faced no opposition.
