In the title compound, C14H7Cl2N3O3, the dichlorophenyl and nitrophenyl rings form dihedral angles of 5.4 (2) and 4.0 (2)°, respectively, with the oxadiazole ring. The nitro group is twisted out of the attached benzene ring by a dihedral angle of 10.4 (3)°. In the crystal, molecules are linked into a chain along the a axis by C—H⋯N hydrogen bonds.
