Nimrod (Hebrew נמרד Nimrod or Nimrōdh) was a king of Assyria mentioned in the Book of Genesis in the Bible. According to Hebrew traditions, he was of Mizraim by mother but came from Cush son of Ham and expanded Asshur which he inherited. His name has become proverbial as that of a "mighty hunter." His "kingdom" comprised Babel (Sumerian logogram Nun.Ki.), Erech, Accad, and Calneh, in the land of Shinar, otherwise known as the land of Nimrod (Gen. x. 8-10; I Chron. i. 10; Micah v. 5)

Nimrod is credited with building the Tower of Babel in order to establish his own cult. Historians have linked the Biblical name with Ninnu (with the epithet Enmersi) of the city of Lagash and subsequently also to EnmerKar of Uruk; Ningirsu of the early dynastic Sumerians; Asar son of Enki of The Sumerians of Eridu and subsequently the Egyptian Osiris Asshur and Phoenician Rashap & Canaanite Reshpu (thus also the constellation Orion); Baal; and the Assyrian Ninurta -while the Babylonians obviously linked him with the Mesopotanian deity Marduk the Sumerian Dumuzi and the Mesopotamian king Ninus of Greek legend husband of Semiramis. 'Nimrod' is translated 'Nebrod' in the Septuagint. He is later attributed to Zoroaster by Clementine "Of this family there was born in due time a certain one, who took up with magical practices, by name Nebrod, who chose, giant-like, to devise things in opposition to God. Him the Greeks have called Zoroaster."

Josephus says:

"Now it was Nimrod who excited them to such an affront and contempt of God. He was the grandson of Ham, the son of Noah, a bold man, and of great strength of hand. He persuaded them not to ascribe it to God, as if it was through his means they were happy, but to believe that it was their own courage which procured that happiness. He also gradually changed the government into tyranny, seeing no other way of turning men from the fear of God, but to bring them into a constant dependence on his power..."

"Now the multitude were very ready to follow the determination of Nimrod, and to esteem it a piece of cowardice to submit to God; and they built a tower, neither sparing any pains, nor being in any degree negligent about the work: and, by reason of the multitude of hands employed in it, it grew very high, sooner than any one could expect; but the thickness of it was so great, and it was so strongly built, that thereby its great height seemed, upon the view, to be less than it really was. It was built of burnt brick, cemented together with mortar, made of bitumen, that it might not be liable to admit water. When God saw that they acted so madly, he did not resolve to destroy them utterly, since they were not grown wiser by the destruction of the former sinners; but he caused a tumult among them, by producing in them divers languages, and causing that, through the multitude of those languages, they should not be able to understand one another. The place wherein they built the tower is now called Babylon, because of the confusion of that language which they readily understood before; for the Hebrews mean by the word Babel, confusion..."

Other traditions suggest that Nimrod died a violent death. One tradition says that he was killed by a wild animal. Another says that Shem killed him because he had led the people into the worship of Baal. According to ancient Egyptian and Babylonian traditions, his mother was Semiramis; sometimes Semiramis is referred to as the mother of Nimrod, and sometimes as his wife, leading to the belief that Nimrod married his mother. Also according to these traditions, Semiramis, who rose to greatness because of her son, was presented with a difficulty when her son died, so instead she pronounced him to be a god, so that she herself would become a goddess.

One tradition says that after Nimrod was killed, Semiramis claimed that an evergreen tree sprouted from a tree stump, which she said indicated the entry of new life into the deceased Nimrod; every year on the anniversary of Nimrod's birth (December 25th) they would leave gifts at this evergreen tree. This is presented by some as a possible explanation the origin of the Christmas tree. Even though Semiramis claimed to be a virgin she had another son, named Tammuz, who she said was the reincarnation of Nimrod. She became known as the "Virgin Mother", "Holy Mother" and the "Queen of Heaven" and was symbolized by the Moon. So began the worship of Semiramis and the child-god, and the whole paraphernalia of the Babylonian religious system.

After the decline of Babylon, the religion was transported to Egypt where the people worshipped Isis and her son Osiris (otherwise known as Horus). The same mother and child deities appeared in Pagan Rome as Fortuna and Jupiter, and in Greece as Ceres, the Great Mother, with the babe at her breast, or as Irene, the goddess of Peace, with the boy Plutus in her arms.

In Hungarian mythology the ancestors of Huns and Magyars were the twin sons of Nimrod and Eneth.
