The South Tyrolean Army Group (German: Heeresgruppe Südtirol) was an Army Group of the Austro-Hungarian Army, which operated in South Tyrol against Italy, between 1 March 1917 and the end of the war during World War I. It was also called Army Group Conrad (German: Heeresgruppe Conrad) and Army Group Archduke Joseph (German: Heeresgruppe Erzherzog Joseph) after its commanders.
The Army Group participated in support of the German 14th Army during the successful Battle of Caporetto (October – November 1917), but it was badly defeated during the Battle of the Piave River (June 1918). The Army Group disintegrated completely during the Battle of Vittorio Veneto (October–November 1918).
