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

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]

In addition to the Cape York meteorite it has been reported from:[3]
