The king of Assyria, called the governor or viceroy of Assyria in the Early and Old periods, was the ruler of the ancient Mesopotamian kingdom of Assyria, which existed from approximately the 26th century BC to the 7th century BC. All modern lists of Assyrian kings generally follow the Assyrian King List, a list kept and developed by the ancient Assyrians themselves over the course of several centuries. Though some parts of the list are probably fictional, the list accords well with Hittite, Babylonian and ancient Egyptian king lists and with the archaeological record, and is generally considered reliable for the age.

The king of Babylon was the ruler of the ancient Mesopotamian city of Babylon and its kingdom, Babylonia, which existed as an independent realm from the 19th century BC to its fall in the 6th century BC. For the majority of its existence as an independent kingdom, Babylon ruled most of southern Mesopotamia, composed of the ancient regions of Sumer and Akkad. The city experienced two major periods of ascendancy, when Babylonian kings rose to dominate large parts of the Ancient Near East; the First Babylonian Empire and the Second Babylonian Empire.

The king of Iraq was Iraq's head of state and monarch from 1921 to 1958. He served as the head of the Iraqi monarchy—the House of Hashim. The king was addressed as His Majesty.

This text is preserved in several recensions. The list of kings is sequential, although modern research indicates many were contemporaries, reflecting the belief that kingship was handed down by the gods and could be transferred from one city to another, asserting to a hegemony in the region.
