Nitrobenzenes are a group of nitro compounds consisting of one or more nitro groups as substituents on a benzene core. They have the formula C₆H_6–n(NO₂)_n, where n = 1–6 is the number of nitro groups. Depending on the number of nitro groups, there may be several constitutional isomers possible.

• Mononitrobenzene
• Dinitrobenzene
  • 1,2-Dinitrobenzene
  • 1,3-Dinitrobenzene
  • 1,4-Dinitrobenzene
• Trinitrobenzene
  • 1,2,3-Trinitrobenzene
  • 1,2,4-Trinitrobenzene
  • 1,3,5-Trinitrobenzene
• Tetranitrobenzene
  • 1,2,3,4-Tetranitrobenzene
  • 1,2,3,5-Tetranitrobenzene
