Mononitrotoluene, or methylnitrobenzene or nitrotoluene (MNT or NT), is a group of three 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. All are pale yellow with faint fragrances:

• ortho-nitrotoluene (ONT), o-nitrotoluene, or 2-nitrotoluene. m.p. = -10.4 °C
• meta-nitrotoluene (MNT), m-nitrotoluene, or 3-nitrotoluene. m.p. = 16 °C
• para-nitrotoluene (PNT), p-nitrotoluene, or 4-nitrotoluene. m.p. = 44.5 °C

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.
