1,8-Bis(dimethylamino)naphthalene is an organic compound with the formula C₁₀H₆(NMe₂)₂ (Me = methyl). It is classified as a peri-naphthalene, i.e. a 1,8-disubstituted derivative of naphthalene. Owing to its unusual structure, it exhibits exceptional basicity. It is often referred by the trade name Proton Sponge, a trademark of Sigma-Aldrich.
