Mononitrotoluene, or methylnitrobenzene or nitrotoluene (MNT or NT), is a group of 3 organic compounds, a nitro derivative of toluene (or alternatively a methyl derivative of nitrobenzene). Its chemical formula is C₆H₄(CH₃)(NO₂).

Mononitrotoluene comes in three isomers, differing by the relative position of the methyl and nitro groups:

ortho-nitrotoluene (ONT), o-nitrotoluene, or 2-nitrotoluene, CAS number [88-72-2]. It is a pale yellow liquid with a subtle, characteristic smell. It is non-hygroscopic and noncorrosive.

meta-nitrotoluene (MNT), m-nitrotoluene, or 3-nitrotoluene, CAS number [99-08-1]. It is a yellowish-greenish to yellow liquid with weak fragrance.

para-nitrotoluene (PNT), p-nitrotoluene, or 4-nitrotoluene, CAS number [99-99-0]. It is a pale yellow material forming rhombic crystals and has a somewhat pleasant, characteristic smell. It is almost insoluble in water.

Typical use of nitrotoluene is in production of pigments, antioxidants, agricultural chemicals, and photographic chemicals.

ortho-Mononitrotoluene and para-mononitrotoluene can be also used as detection taggants for explosive detection.
