Malachite green is an organic compound that is used as a dyestuff and controversially as an antimicrobial in aquaculture.  Malachite green is traditionally used as a dye for materials such as silk, leather, and paper.  Despite its name the dye is not prepared from the mineral malachite, and the name just comes from the similarity of color.

Malachite green is classified in the dyestuff industry as a triarylmethane dye and also using in pigment industry.  Formally, malachite green refers to the chloride salt [C6H5C(C6H4N(CH3)2)2]Cl, although the term malachite green is used loosely and often just refers to the colored cation.  The oxalate salt is also marketed.  The anions have no effect on the color.  The intense green color of the cation results from a strong absorption band at 621 nm (extinction coefficient of 105 M−1 cm−1).
