Bucephalus (; ; – June 326 BC) or Bucephalas, was the horse of Alexander the Great, and one of the most famous horses of classical antiquity. According to the Alexander Romance (1.15), the name "Bucephalus" literally means "ox-headed" (from and ), and supposedly comes from a brand (or scar) on the thigh of the horse that looked like an ox's head.
Ancient historical accounts state that Bucephalus's breed was that of the "best Thessalian strain", and that he died in what is now Punjab, Pakistan, after the Battle of the Hydaspes in 326 BC. Alexander was so grieved at the loss of his horse that he named one of the many cities he founded after him, as Alexandria Bucephalus.

A massive creature with a massive head, Bucephalus is described as having a black coat with a large white star on his brow. He is also supposed to have had a "wall eye" (blue eye), and his breeding was that of the "best Thessalian strain".
Plutarch says that in 344 BC, at twelve or thirteen years of age, Alexander of Macedonia won the horse by making a wager with his father: a horse dealer named Philonicus the Thessalian offered Bucephalus to King Philip II for the remarkably high sum of 13 talents.
