Nitryl azide (tetranitrogen dioxide) is an inorganic compound with the chemical formula N3−NO2. It is an unstable nitrogen oxide consisting of a covalent nitrogen–nitrogen bond between a nitro group and an azide group. It has been detected by infrared spectroscopy as a short-lived product of the reaction between sodium azide and nitronium hexafluoroantimonate: It is also the product of nitryl chloride and silver azide. Nitryl azide can also be obtained from two nitrous oxide molecules at 298 K, but will quickly decompose back into the two original N
2O molecules.

The compound quickly decomposes to form two nitrous oxide molecules. Calculations suggest that this process occurs via an oxatetrazole oxide intermediate:
