In the title hydrated 1:1 adduct, C8H8O2·C14H13N3O·H2O, the Schiff base mol­ecule exists in an E conformation with respect to the N=C bond [1.2843 (13) Å] and the dihedral angle between the pyridine ring and the benzene ring is 1.04 (5)°. In the crystal, mol­ecules are linked by N—H⋯O, C—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds into sheets lying parallel to the ab plane. The crystal structure also features π–π inter­actions with centroid–centroid distances of 3.6224 (6) and 3.7121 (6) Å.
