In the title compound, C16H17N3O·H2O, the isonicotinohydrazide mol­ecule adopts an E conformation about the central C=N double bond. The dihedral angle between the pyridine and the benzene rings is 54.56 (15)°. In the crystal, mol­ecules are connected via N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds, forming a three-dimensional network.
