Midas (/ˈmaɪdəs/; Greek: Μίδας) is the name of at least three members of the royal house of Phrygia.

The most famous King Midas is popularly remembered in Greek mythology for his ability to turn everything he touched into gold. This came to be called the golden touch, or the Midas touch. The Phrygian city Midaeum was presumably named after this Midas, and this is probably also the Midas that according to Pausanias founded Ancyra. According to Aristotle, legend held that Midas died of starvation as a result of his "vain prayer" for the gold touch. The legends told about this Midas and his father Gordias, credited with founding the Phrygian capital city Gordium and tying the Gordian Knot, indicate that they were believed to have lived sometime in the 2nd millennium BC, well before the Trojan War. However, Homer does not mention Midas or Gordias, while instead mentioning two other Phrygian kings, Mygdon and Otreus.
