The name of Imatra is thought to derive from a pre-Finno-Ugric language. The lightning symbols on Imatra's coat of arms refer to the power plants that were built in the early 1920s at the Tainionskoski and Imatrankoski rapids. The coat of arms was designed by Olof Eriksson and approved by the Imatra Town Council on 9 August 1950. The Ministry of the Interior approved the coat of arms for use on 25 October of the same year.
