Stalag III-D was a World War II German Army prisoner-of-war camp located in Berlin.

The camp was established on 14 August 1940 on the corner of Landweg and Osdorfer Straße in Berlin-Lichterfelde.

The Germans particularly sought out former members and sympathizers of the British Union of Fascists, but the attempt was largely a failure with the unit never numbering more than about 30 men at any time.

A small number of men from these camps also joined the staff of the Ministry of Propaganda, working for radio stations and magazines.

[3] A similar camp at Friesack, designated Stalag XX-A (301), was established to recruit Irishmen serving in the British Army.
