Maahes (Mahes, Mihos, Miysis, Mysis) was the ancient Egyptian lion-god of war. Both a god of war and a guardian and a lord of the horizon. He was believed to help Ra fight against Apep in the solar barque each night, a god who protected the pharaoh while he was in battle. By Greek times, he was attributed as being a god of storms and winds. He also had links to perfumes and oils. Maahes was a god who seems to have first appeared in the New Kingdom, and is thought to have been a deity of foreign origin.

Maahes was thought to be the guardian of sacred places, and the one who attacks captive enemies. He protected the innocent dead and condemned the damned. He was thought to be one of Osiris' executioners, and a defender of the solar barque against the attack of the snake-demon Apep and his followers. He protected the pharaoh while he was in battle, just as he protected the sun god Ra. He was also a god, and a protector of the horizon, due to his leonine form - lions were connected to the horizon by the Egyptian mind. He was also thought to be the personification of the summer heat, just as the Eye of Ra - different lioness goddesses - were thought to represent the burning heat of the sun.
