Awaruite is a naturally occurring alloy of nickel and iron with a composition from Ni2Fe to Ni3Fe.

Awaruite occurs in river placer deposits derived from serpentinized peridotites and ophiolites. It also occurs as a rare component of meteorites. It occurs in association with native gold and magnetite in placers; with copper, heazlewoodite, pentlandite, violarite, chromite, and millerite in peridotites; with kamacite, allabogdanite, schreibersite and graphite in meteorites.
