Hapkeite is a mineral meteorite on the Arabian peninsula. The meteorite is believed to originate from the Moon ; specifically, it appears to be a fragment of lunar highland breccia, and it is similar to other silicon-iron minerals found on Earth. An impact on the Moon is thought to have launched the partially molten or vaporized material into orbit.

Due to its 1:2 composition of silicon-iron, hapkeite was given the chemical formula. It occurs as opaque, yellowish to silvery microscopic isometric crystals.

It is named after Bruce Hapke , who predicted the presence and importance of vapor-deposited coatings on lunar soil grains (space weathering

Beside hapkeite, other natural iron silicide minerals include gupeiite, luobusaite, and zangboite
