Mithril is a fictional metal from J.R.R. Tolkien's Middle-earth legendarium, particularly known from his works like The Lord of the Rings. It is described as a lightweight, silver-like material that is stronger than steel, making it highly sought after for crafting armor and weapons. In the stories, mithril is primarily mined in the Moria region by the Dwarves, who value it for its beauty and durability. The most famous mithril item is the shirt worn by Frodo Baggins, which provides exceptional protection while remaining light and comfortable.
