In the title Schiff base, C(22)H(20)N(2)O(2), the benzene ring forms dihedral angles of 53.92 (1) and 3.62 (1)° with the two salicylaldimine groups. There are two strong O-H⋯N intra-molecular hydrogen bonds. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds and π-π stacking inter-actions (average distance 3.39 Å).
