2,4-Diaminotoluene is an organic compound with the formula C₆H₃(NH₂)₂CH₃. It is one isomer of six with this formula. It is a white solid although commercial samples are often yellow-tan. It is prepared by hydrogenation of 2,4-dinitrotoluene using a nickel catalyst. Commercial samples often contain up to 20% of the 2,6-isomer.

It is mainly used as a precursor to toluene diisocyanate, a precursor to polyurethane.

Its reaction with benzenediazonium chloride gives the cationic azo dye Basic Orange 1. Condensation of 2,4-diaminotoluene with acetaldehyde gives the acridine dye called Basic Yellow 9.
