Alexandropolis () in the Thracian region of Maedians, was the first town founded by Alexander the Great after he defeated a local Thracian tribe as a regent (, epitropos) of Macedon in 340 BC. Its name was chosen by analogy with Philippopolis, the town of Thrace founded by Alexander's father, Philip II. He expelled the locals and settled a mixed population. The location of Alexandropolis is unknown, suggesting that a Thracian raid may have caused its disappearance from history (See Zopyrion). Tarn claims Alexandropolis was a military colony rather than a polis.
