Hexanitrobenzene, also known as HNB, is a nitrobenzene compound in which six nitro groups are bonded to all six positions of a central benzene ring. It is a high-density explosive compound with chemical formula , obtained by oxidizing the amine group of pentanitroaniline with hydrogen peroxide in sulfuric acid.

== Properties == thumb|left|Perspective view of the crystal structure of hexanitrobenzene, showing the rotation of the nitro groups.Left: Ball-and-stick structure.Right: van der Waals space-filling structure. The stable conformation of this molecule has the nitro groups rotated out of the plane of the central benzene ring. The molecule adopts a propeller-like conformation in which the nitro groups are rotated about 53° from planar.
