The coat of arms of the Estonian SSR was adopted in 1940 by the government of the Estonian SSR. It features a sunrise accented by sunbeams, the hammer and sickle for the victory of communism and the "world-wide socialist community of states", and the red star to represent the affiliation to communism. The emblem consists mainly of the colors red, yellow and green.
In the lower part the interlaced text reads, in Estonian Eesti NSV (for Eesti Nõukogude Sotsialistlik Vabariik, Estonian Soviet Socialist Republic). To the right, rye stalks encircle the center of the coat of arms, and to the left arcs a branch of a coniferous tree.
The banner bears the USSR State motto ("Proletarians of all countries, unite!") in both Estonian (Kõigi maade proletaarlased, ühinege!) and Russian (Пролетарии всех стран, соединяйтесь! Proletarii vsekh stran, soyedinyaytes′!).
The coat of arms of independent Estonia was restored in 1990.
