Blazon: „Gules, enté en point Or charged with a torteaux accompanied by two bezants.“ 
The arms were officially granted on May 21, 1952. The arms is derived from the arms of the Lords von Goldegg, who built the local Klammstein Castle in the 13th century. The three roundels are taken from the arms of the Nonnberg Convent, to which the village of Unterberg in the municipality belonged for a long period of time.
