The Mythril Mines are a location in Final Fantasy III. They are located nearby Kazus, where an entrance to them can be found. They are not part of the main storyline. Two Mythril Swords can be found in chests behind a hidden passage opened by activating a secret switch. The switch, however, can only be triggered after the party has defeated Djinn in the Sealed Cave.

The word "mythril" or "mithril" is a metal found in many fantasy worlds. It was originally introduced by the fantasy writings of J. R. R. Tolkien, being present in his Middle-earth. It resembles silver but is stronger than steel, and much lighter in weight than either. The author first wrote of it in The Lord of the Rings, and it is retrospectively mentioned in the third, revised edition of The Hobbit in 1966. In the first 1937 edition, the mail shirt given to Bilbo is described as being made of "silvered steel". The name mithril comes from two words in Sindarin—mith, meaning "grey" or "mist", and ril meaning "glitter".
