Stalag XVIII-A was a World War II German Army (Wehrmacht) prisoner-of-war camp located to the south of the town of Wolfsberg, in the southern Austrian state of Carinthia, then a part of Nazi Germany.

The camp, first designated Oflag XVIII-B, was opened at the site of a former parade ground on 19 October 1939, after the German invasion of Poland.

[2] In June 1942, to ease overcrowding, three new barracks were built, and 400 British NCOs were transferred to Stalag XVIII-B at Spittal.

[2] In August 1944, according to a Red Cross report, there were 313 Arbeitskommandos attached to Stalag XVIII-A, which were split fairly equally between Landwirtschaft (agriculture or forestry) and Gewerbliche Wirtschaft (trade and industry).

That day the Kommandant, Hauptmann Steiner, had handed over control of the camp to the Senior British Medical Officer and the "Men of Confidence".

Over the next few weeks the prisoners were transported via Klagenfurt to transit camps in Bari and Naples, from where they were eventually repatriated.
