Myndus (/ˈmɪndəs/) or Myndos (Greek: Μύνδος) was an ancient Dorian colony of Troezen, on the coast of Caria in Asia Minor, (Turkey), sited on the Bodrum Peninsula, a few miles northwest of Halicarnassus.

Pliny, however, mentions both Myndus and Neapolis as two different towns, and modern scholars differentiate the two.

[1] The cynic philosopher Diogenes of Sinope visited Myndos and noticed how large the city gates were, relative to the town; he cynically remarked; "Oh men of Myndos, I urge you to shut the city gates, as your town might exit from these!".

Herodotus relates the story of how a captain from Myndus, Scylax, was found to have left no guards on his ship while a Persian force was preparing to attack the island of Naxos.

The Persian commander, Megabates, flew into a rage and had him put in stocks, at which point Aristagoras, a tyrant from Miletus helping several Naxian oligarchs to retake Naxos, discovered what had happened to his guest-friend Scylax.

Pleading with Megabates to no avail for Scylax, he released him anyway, incurring the Persian commander's wrath.

The consequence of this falling out was that, according to Herodotus, Megabates warned the Naxians of what was afoot, ruining the expedition and in turn Aristagoras who, with nowhere to go, stirred up the Ionian Revolt.

This is a classic example of Ionian αταξιη (lack of discipline, disorder, licentiousness), a charge commonly levelled at them, especially in the 5th century by Athens.

32) states that the wine grown in the district of Myndus was good for digestion.

Remains of the city are visible in and around Gümüşlük and in the adjacent waters; it is supposed that some unrecorded earthquake caused seafront sections of the ancient town to be submerged.
