The Seleucid–Mauryan War was fought between 305 and 303 BC. It started when Seleucus I Nicator of the Seleucid Empire sought to retake the Indian satrapies of the Macedonian Empire, which had been occupied by Emperor Chandragupta Maurya, of the Maurya Empire.

Seleucus I Nicator was a Macedonian Greek general, officer and successor of Alexander the Great who went on to found the eponymous Seleucid Empire, led by the Seleucid dynasty. Initially a secondary player in the power struggles following Alexander's death, Seleucus rose to become the total ruler of Asia Minor, Syria, Mesopotamia, and the Iranian plateau, assuming the title of basileus (emperor). The Seleucid Empire was one of the major powers of the Hellenistic world, until it was overcome by the Roman Republic and Parthian Empire in the late second and early first centuries BC.
