The XIX (2nd Royal Saxon) Army Corps / XIX AK () was a Saxon corps level command of the German Army, before and during World War I. As the German Army expanded in the latter part of the 19th Century and early part of the 20th Century, the XIX Army Corps was set up on 1 April 1899 in Leipzig as the Generalkommando (headquarters) for the western part of the Kingdom of Saxony (districts of Leipzig, Chemnitz and Zwickau). It took over command of 24th (2nd Royal Saxon) Division from XII (1st Royal Saxon) Corps and the newly formed 40th (4th Royal Saxon) Division.
