The Italian Eleventh Army was one of the armies of the Royal Italian Army during World War II. It was formed on 9 November 1940 out of the 11th Army Corps, then based in Italian-occuped Albania and engaged in operations against Greece alongside the 9th Army. Its engagement against the Greeks lasted until the fall of Greece in April 1941. Thereafter the Eleventh Army assumed duties of occupation in Greece, headquartered in Athens under General Carlo Geloso. It was forcibly disbanded by the German Army in September 1943, after the Italian capitulation.
