Provided is a method for producing a deuterated aromatic compound and a deuterated reaction composition. The method includes performing a deuterated reaction of an aromatic compound including one or more hydrocarbon aromatic rings using a solution comprising heavy water, an organic compound which can be hydrolyzed by the heavy water, the aromatic compound, and an organic solvent. The method has an advantage in that impurities due to hydrogen gas are not generated, the deuterium substitution rate is high, and the deuterated reaction can be performed under a lower pressure and a lower temperature.
