The title compound, C20H26N4O2·CH3OH, was prepared by the reaction of 4-diethyl­amino-2-hy­droxy­benzaldehyde with 4-(dimethyl­amino)­benzohydrazide. The dihedral angle between the two benzene rings is 13.6 (3)° and an intra­molecular O—H⋯N hydrogen bond generates an S(6) ring. In the crystal, the hydrazone and methanol mol­ecules are linked through inter­molecular O—H⋯O and N—H⋯O hydrogen bonds, forming chains along a.
