German Democratic Republic postage stamps

German Democratic Republic postage stamps are the postal issues released for East Germany, officially known as the German Democratic Republic. They were issued by the Deutsche Post of the GDR, which operated as a postal service provider from 1949 to 1990. Following the interim period when the Deutsche Post functioned under Allied control from 1945 to 1949, the GDR administration maintained its own separate postal system, functioning alongside other German providers of the era such as the Deutsche Bundespost and the Deutsche Bundespost Berlin.

The period of use for these issues spanned from the establishment of the state postal authority in 1949 until 1990, ending at German reunification. All stamp issues for the German Democratic Republic concluded in 1990. From 1990 onward, separate East German postal emissions were discontinued, and the postage stamps of the united Germany were used across the reunified nation. The designs of GDR postage stamps encompassed a wide selection of motifs, focusing heavily on industry, culture, anniversaries, and political subjects. Philatelic issues regularly featured notable individuals, many of whom appeared across multiple stamp releases. These portraits depicted scientists such as Albert Einstein and Marie Curie, composers including Johann Sebastian Bach and Ludwig van Beethoven, writers such as Johann Wolfgang von Goethe and Bertolt Brecht, and philosophers like G. W. F. Hegel. The issues also honoured socialist and working-class movement figures such as Friedrich Engels and August Bebel, German resistance members, cosmonauts like Yuri Gagarin, and international leaders. A definitive distinguishing feature of this stamp type is the state inscription, which differentiates East German issues from those produced by the Federal Republic.
