m-Phenylenediamine, also called 1,3-diaminobenzene, is an organic compound with the formula C6H4(NH2)2. It is an isomer of o-phenylenediamine and p-phenylenediamine. It is a colourless solid.

m-Phenylenediamine is produced by hydrogenation of 1,3-dinitrobenzene. The dinitrobenzene is prepared by dinitration of benzene.

m-Phenylenediamine is used in the preparation various polymers including aramid fibers, epoxy resins, wire enamel coatings and polyurea elastomers. Other uses for m-phenylenediamine include as an accelerator for adhesive resins, and as a component of dyes for leather and textiles.Basic Brown 1 (Bismarck Brown), Basic Orange 2, Direct Black 38, and Developed Black BH In hair-dying, m-phenylenediamine is a "coupling agent", used to produce blue colors.
