The Prisoner of War Medal 1940–1945 (French: Médaille du Prisonnier de Guerre 1940–1945, Dutch: Krijgsgevangenenmedaille 1940–1945) was a Belgian war service medal established by royal decree on 20 October 1947 and awarded to all members of the Belgian Armed Forces imprisoned by Axis Forces during the Second World War.

Two triangular laurel leaves protrude from between the cross arms fanning out.

A ring of barbed wire encircles the cross along the entire circumference 3mm from the medal's edge.

The reverse bore a guard tower and prison camp fence surrounded by a chain along the entire circumference 3mm from the medal's edge.

Years of imprisonment were denoted on the ribbon by small striated metal bars.
