Vanadium nitride, VN, is a chemical compound of vanadium and nitrogen.

Vanadium nitride is formed during the nitriding of steel and increases wear resistance.[1] Another phase, V2N, also referred to as vanadium nitride, can be formed along with VN during nitriding.[2] VN has a cubic, rock salt structure. There is also a low temperature form which contains V4 clusters.[3]

It is a strong-coupled superconductor.[4] Nanocrystalline vanadium nitride has been claimed to have potential for use in supercapacitors.[5]
