Alexander () was Tyrant or Despot of Pherae in Thessaly, ruling from 369 to c. 356 BC. Following the assassination of Jason, the tyrant of Pherae and Tagus of Thessaly, in 370 BC, his brother Polydorus ruled for a year, but he was then poisoned by another brother (or nephew, according to Xenephon), Alexander. Alexander governed tyrannically and was constantly seeking to control Thessaly and the kingdom of Macedonia. He also engaged in piratical raids on Attica. Alexander was murdered by the brothers of his wife, Thebe, as it was said that she lived in fear of her husband and hated Alexander's cruel and brutal character. Reign The accounts of how Alexander came to power vary somewhat in minor points.

Therefore, they applied for help from Alexander II of Macedon. Alexander prepared to meet his enemy in Macedonia, but the king anticipated him, and, reaching Larissa, was admitted into the city. Alexander withdrew to Pherae whilst the Macedonian King placed a garrison in Larissa, as well as in Crannon, which had also come over to him. But once the bulk of the Macedonian army had retired, the states of Thessaly feared the return and vengeance of Alexander, and so sent for aid to Thebes, whose policy it was to put a check on any neighbour who might otherwise become too formidable. Thebes accordingly dispatched Pelopidas to the aid of Thessaly. On arrival of Pelopidas at Larissa, whence according to Diodorus, he dislodged the Macedonian garrison, Alexander presented himself and offered submission.
