In early Egyptian mythology, Anhur (also spelled Onuris, Onouris, An-Her, Anhuret, Han-Her, Inhert) was a god of war who was worshipped in the Egyptian area of Abydos, and particularly in Thinis. Myths told that he had brought his wife, Mehit, who was his female counterpart, from Nubia, and his name reflects this—it means (one who) leads back the distant one.

One of his titles was Slayer of Enemies. Anhur was depicted as a bearded man wearing a robe and a headdress with four feathers, holding a spear or lance, or occasionally as a lion-headed god (representing strength and power). In some depictions, the robe was more similar to a kilt.

Due to his position as a war god, he was patron of the ancient Egyptian army, and the personification of royal warriors. Indeed, at festivals honoring him, mock battles were staged. During the Roman era the Emperor Tiberius was depicted on the walls of Egyptian temples wearing the distinctive four-plumed crown of Anhur.

The Greeks equated Anhur to their god of war, Ares. In the legend of Olympian gods fleeing from Typhon and taking animal form in Egypt, Ares was said to have taken the form of a fish as Lepidotus or Onuris.

Anhur's name also could mean Sky Bearer and, due to the shared headdress, Anhur was later identified with Shu, becoming Anhur-Shu. He is the son of Ra and brother of Tefnut if identified as Shu.
