Tetrachloro-m-xylene (tetrachlorometaxylene, or TCMX) is the organochlorine compound with the formula C₆Cl₄(CH₃)₂. It is the chlorinated derivative of m-xylene in which the four aromatic hydrogen atoms are replaced by chlorine. It is prepared by ferric chloride-catalyzed reaction of the xylene with chlorine.^[1]

TCMX is used as an internal standard in the analysis of organochlorides, particularly organochloride pesticides.^[2]^[3]
