2-Nitronaphthalene is an organic compound with the formula {{Chem2|C10H7NO2}}. It is one of two isomers of nitronaphthalene, the other being 1-nitronaphthalene. 2-Nitronaphthalene is produced in very low yields upon nitration of naphthalene, but it can be more efficiently obtained via the diazotization of 2-aminonaphthalene.{{Ullmann |doi=10.1002/14356007.a17_411|title=Nitro Compounds, Aromatic |year=2000 |last1=Booth |first1=Gerald |isbn=3527306730 }}
