The Army Group Hindenburg (German: Heeresgruppe Hindenburg) was an Army Group of the German Army, which operated in the Baltics against Russia between 5 August 1915 and 30 July 1916 during World War I, under command of Ober Ost Paul von Hindenburg.
It was renamed Army Group Eichhorn when Hermann von Eichhorn replaced Hindenburg on 3 July 1916 and remained in place until 30 March 1918.
