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] The low-temperature phase results from a dynamic instability, when the energy of vibrational modes in the high-temperature NaCl-structure phase, are reduced below zero.^[4]

It is a strong-coupled superconductor.^[5] Nanocrystalline vanadium nitride has been claimed to have potential for use in supercapacitors.^[6] The properties of vanadium nitride depend sensitively on the stoichiometry of the material.^[7]
