Carlsbergite is a nitride mineral that has the chemical formula CrN,[1] or chromium nitride.

It is named after the Carlsberg Foundation which backed the recovery of the Agpalilik fragment of the Cape York meteorite in which the mineral was first described.[1]

It occurs in meteorites along the grain boundaries of kamacite or troilite in the form of tiny plates.[1] It occurs associated with kamacite, taenite, daubreelite, troilite and sphalerite.[2]
