The 16th Army () was a World War II field army. It took part in the Battle of France. It was then deployed with Army Group North during Operation Barbarossa, the German invasion of the Soviet Union. It fought its way into northern Russia where in January 1942 part of it was encircled by the Soviets near Demyansk. Hitler forbade a withdrawal and the Army was re-supplied by air until a land corridor was opened in April 1942. It was subsequently involved in the siege of Leningrad. The Soviets relieved Leningrad in January 1944.
