Nitryl azide (tetranitrogen dioxide) is an inorganic compound with the chemical formula {{chem2|N3\sNO2|auto=1}}. 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:{{cite journal |title= Reaction between azide and nitronium ions.

The compound quickly decomposes to form nitrous oxide. Calculations suggest that this process occurs via an oxatetrazole oxide intermediate:{{cite journal |title= Gaseous nitryl azide N₄O₂: A joint theoretical and experimental study |first1= Xiaoqing |last1= Zeng |first2= Maofo |last2= Ge |first3= Zheng |last3= Sun |first4= Jiang |last4= Bian |first5= Dianxun |last5= Wang |journal= Journal of Molecular Structure |volume= 840 |year= 2007 |issue= 1–3 |pages= 59–65 |doi= 10.1016/j.molstruc.2006.11.034|bibcode= 2007JMoSt.840...59Z }}
