Shalmaneser IV was the king of the Neo-Assyrian Empire from 783 BC to his death in 773 BC. Shalmaneser was the son and successor of his predecessor, Adad-nirari III, and ruled during a period of Assyrian decline from which few sources survive. As such his reign, other than broad political developments, is poorly known. Shalmaneser's time was marked both by an increase in the power held by Assyrian officials relative to that of the king and Assyria's enemies growing increasingly powerful. Most of Shalmaneser's military efforts were spent warring against the Kingdom of Urartu in the north, which during this time was reaching the peak of its power.

The Neo-Assyrian Empire was the fourth and penultimate stage of ancient Assyrian history. Beginning with the accession of Adad-nirari II in 911 BC, the Neo-Assyrian Empire grew to dominate the ancient Near East throughout much of the 8th and 7th centuries BC, becoming the largest empire in history up to that point. Because of its geopolitical dominance and ideology based in world domination, the Neo-Assyrian Empire is by many researchers regarded to have been the first world empire in history. It influenced other empires of the ancient world culturally, administratively, and militarily, including the Babylonians, the Achaemenids, and the Seleucids. At its height, the empire was the strongest military power in the world and ruled over all of Mesopotamia, the Levant and Egypt, as well as parts of Anatolia, Arabia and modern-day Iran and Armenia.
