Mahtan was an elf of the Noldor who was a great craftsman and smith in Valinor. He studied under Aulë, learning how to work with both stone and metal.

Mahtan later passed on his vast knowledge to Fëanor, who in later years would use that knowledge and skill to make weapons and armor, much to Mahtan's chagrin.

Mahtan was also the father of Fëanor's wife, Nerdanel.
