PROBLEM TO BE SOLVED: To provide a method for producing a chlorinated aromatic compound, being excellent from a viewpoint of energy saving. SOLUTION: The method for producing the chlorinated aromatic compound comprises a chlorination step for obtaining the chlorinated aromatic compound and hydrogen chloride by reacting an aromatic compound with chlorine and a chlorinated aromatic compound-refining step for obtaining the refined chlorinated aromatic compound by refining a reaction mixture obtained in the chlorinated aromatic compound-concentrating step. In the production method, the aromatic compound fed as a raw material to the chlorination step is heated by heat which the chlorinated aromatic compound obtained in the chlorinated aromatic compound-refining step has. In the method for reacting the aromatic compound with chlorine, the molar ratio (aromatic compound/chlorine) of the aromatic compound to chlorine is≥3 and the reaction temperature is 25-130°C and the reaction pressure is 0.02-0.5 MPa.
