The Nationalsozialistischer Deutscher Reichskriegerbund Kyffhäuser was an umbrella organization for war veterans' and reservists' associations in Germany based in Rüdesheim am Rhein.
It owes its name to the Kyffhäuser Monument, a memorial built on the summit of the 473 m high Kyffhäuser mountain near Bad Frankenhausen in the state of Thuringia in central Germany.
