The asymmetric unit of the the title compound, C7H7ClN2O, contains two mol­ecules in which the chloro­phenyl and the formic hydrazide units are almost planar (r.m.s. deviations of 0.0081 and 0.0100 Å, respectively, in one mol­ecule and 0.0069 and 0.0150 Å in the other) and are oriented with respect to each other at dihedral angles of 56.8 (2) and 56.9 (2)°. In the crystal, the mol­ecules are consolidated in the form of polymeric chains extending along [010]. R33(10) ring motifs exist due to N—H⋯O and N—H⋯N hydrogen bonds.
