The Russian 2nd Army (2-я армия, 2А) was an army-level command of the Imperial Russian Army in World War I. It was formed just prior to the outbreak of hostilities from the units of Warsaw Military District and was mobilized in August 1914. The army was effectively destroyed at Battle of Tannenberg in August 1914. However, it was rebuilt soon thereafter and fought until almost the end of the war.
