Belsen is a village within the German borough of Bergen in the northern part of Celle district on the Lüneburg Heath in Lower Saxony.

The village, whose original site lies about 3 kilometres (1.9 mi) southwest of Bergen, has 331 inhabitants (as at: 31 December 2000).

Between Bergen and Belsen, there were railway ramps onto which prisoners from the incoming goods wagons alighted and from where they had to cover the remaining distance of about 4 kilometres (2.5 mi) to the camp on foot.

The original ramps have been replaced and the current ramps are used today to off-load military vehicles of the British, Dutch, French, German, Belgian, Luxembourg and Polish forces in order to take part in exercises on the NATO military training area of Bergen-Hohne.

After the Second World War, a displaced persons (DP) camp was created in the military base of Lager Hohne (called Bergen-Hohne Station or Hohne Camp during its British tenure), opposite the village.
