The Deutsche Dermatologische Gesellschaft e.V. (DDG, German Dermatological Society; "e.V." meaning "registered association") is a scientific specialized society for dermatology in Germany.^[1] It is a member of the Association of Scientific Medical Societies in Germany (AWMF).

It was founded in 1889 in Prague and comprises almost 3,600 full and associated members. The society is based in Berlin, where they operate a joint office with the BVDD, Berufsverband der Deutschen Dermatologen (Professional Association of Germany's dermatologists). In 1998 these two organizations founded the DDA, Deutsche Dermatologische Akademie (German dermatological academy), which is committed to the continued and advanced education of dermatologists.

The DDG also is represented in the European Academy of Dermatology and Venereology (EADV), the European Dermatology Forum (EDF), the European Society Dermatological Research (ESDR), and the Union of European Union Medical Specialists (UEMS).^[3][4][5]

Commemorating the 70th anniversary of the death of Karl Herxheimer, who was a Jewish dermatologist from Frankfurt am Main in Nazi Germany, the society organized a Karl Herxheimer commemoration lecture on 6 December 2012 and set up a memorial stone in the Jewish graveyard in Frankfurt.

The award of the Karl Herxheimer Medal is the highest honor in German dermatology.^[11] It is given to outstanding scholars in the field of dermatovenerology in memory of the great doctor, teacher and researcher Karl Herxheimer.
