Milos (in Greek, Μήλος, classic Greek: Μῆλος – Melos, Doric Greek: Μάλος – Malos), is a volcanic Greek island in the Aegean Sea, just north of the Sea of Crete. Milos is the southwesternmost island in the Cyclades group.

The island is famous for the statue of Aphrodite (the "Venus de Milo", now in the Louvre), and also for statues of the Greek god Asclepius (now in the British Museum) and the Poseidon and an archaic Apollo in Athens. The Municipality of Milos also includes the uninhabited offshore islands of Antimilos and Akradies. The combined land area is 160.147 km² and the 2001 census population was 4,771 inhabitants.

Obsidian from Milos was a commodity as early as 13,000 years ago. Milos natural glass used for razor sharp "stone tools" was transported well before farming began and later: "There is no early farming village in the Near East that doesn't get obsidian". The material was transported for thousands of miles.

The position of Milos, between mainland Greece and Crete, and its possession of obsidian, made it an important centre of early Aegean civilization. Milos lost its arms-making importance when bronze became the preferred material for the manufacture of weapons.
