The 1st Corps of the Belgian Army (French: 1er Corps d'Armée belge), also known as 1 BE Corps, was a Belgian army corps active during World War I, World War II, and the Cold War.

During the Belgian Campaign of 1940, it initially held defences at Liège but was forced to retreat by the German XVI Panzer Corps. (The Battle of Fort Eben-Emael occurred along the Corps' defensive line.)

During the Cold War, it served initially as an army of occupation in Germany and then as part of NATO's Northern Army Group (NORTHAG). The corps headquarters was initially established at Yser Caserne, Lüdenscheid, on 15 October 1946. Lieutenant General Jean-Baptiste Piron took command in November 1946. Corps headquarters moved to Haelen Caserne, Junkersdorf, Lindenthal, Cologne, in 1948.

During Exercise Battle Royal in September 1954, the Corps consisted of 1 (BE) Infantry Division and 16 (BE) Armoured Division with 1 Canadian Brigade and 46 Parachute Brigade (16th Airborne Division (United Kingdom)) under command.

The corps' 14th and 20th artillery battalions were supported by the 4th U.S. Army Field Artillery Detachment. The detachment was co-located with the Belgian battalions, in quarters across the street from the Belgian Houthulst Kaserne, on Langenwiedenweg Strasse, Werl, West Germany.

In 1960 the 1st and 16th divisions were transformed into mechanised divisions of the 'Landcent' type. That year, 1st Division at Bensberg consisted of 1st Infantry Brigade (Siegen), 7th Brigade (Spich), and 18th Armoured Brigade (Euskirchen), and 16th Armoured Division consisted of 17th Armoured Brigade (Duren), 16th Infantry Brigade (Ludenscheid) and 4th Infantry Brigade (Soest).
