There was one person and one god known as Boreas in Greek mythology. The mortal was the father of King Haemus of Thrace.

Boreas ("north wind" or "devouring") was the Greek god with that name, one of the Anemoi. He was the son of Eos and Aeolus, brother of Eurus, Notus and Zephyrus. Boreas was usually depicted as a racy old man, winged and very strong.

Boreas had two sons, two daughters, and twelve mares which are said to be able to run across a field of grain without trampling the plants. Pliny (Natural History iv.35 and viii.67) thought that mares might stand with their hindquarters to the North Wind, and bear foals without a stallion. When Athens was threatened by Xerxes, the people prayed to Boreas, who caused winds to sink 400 Persian ships.

He kidnapped Oreithyia, an Athenian princess, from the river llissus and with her fathered the Boreads and Chione.

His Roman mythological equivalent was Aquilo.

The Greeks believed that his home was in Thrace, and Herodotus and Pliny both describe a land beyond the northern wind known as Hyperborei, where people lived in complete happiness to extreme years.

Boreas was the father of Butes.
