In the title molecule, C12H10N2O2, the benzene and pyridine rings form a dihedral angle of 5.01 (8)°. The amide group is twisted by 33.54 (7)° from the plane of the pyridine ring. In the crystal, molecules are linked into centrosymmetric dimers via pairs of O—H⋯N hydrogen bonds. N—H⋯O hydrogen bonds further link dimers related into chains along the b axis.
