1,8-Diaminonaphthalene is an organic compound with the formula C₁₀H₆(NH₂)₂. It is one of the diamine derivatives of naphthalene. It is a colorless solid that darkens in air due to oxidation. It is a precursor to commercial pigments.

It is prepared by reduction of 1,8-dinitronaphthalene, which in turn is obtained as a mixture of isomers by nitration of 1-nitronaphthalene.

Upon treatment with phthalic anhydride derivatives, the diamine converts to phthaloperinones. The derivative from phthalic anhydride itself, Solvent Orange 60, is a useful orange pigments. It is a precursor to 1,8-bis(dimethylamino)naphthalene.
