What was the name of Alexander the Great's horse?

Alexander the Great’s famous horse was Bucephalus.

Bucephalus was a powerful Thessalian horse who became Alexander’s trusted warhorse. According to Plutarch, the horse was considered difficult or impossible to tame because he became frightened by his own shadow. The young Alexander noticed the problem, turned Bucephalus toward the sun, and calmed him before successfully mounting him.

The name Bucephalus means “ox-head” or “ox-headed,” probably referring to the horse’s appearance or to a distinctive mark. Ancient accounts associate him with Alexander from the king’s youth through his campaigns across Asia. He is said to have carried Alexander during major battles, although some details of the traditional story were embellished by later writers.

Bucephalus reportedly died after the Battle of the Hydaspes in 326 BC, in the region of modern Pakistan. Alexander is traditionally said to have founded or named the city of Bucephala in his honour. Pegasus, Sleipnir, and Shadowfax are famous horses from mythology or fiction, not Alexander’s historical mount.
