Lothar König (1906-1946) was a German Jesuit priest and member of the Kreisau Circle of the German Resistance during the Nazi period.
Though multi-denominational, the Kreisau group's opposition to the Hitler regime had a strongly Christian orientation, and looked for a general Christian revival, and reawakening of awareness of the transcendental. Its outlook was rooted both in German romantic and idealist tradition and in the Catholic doctrine of natural law. König would become an important intermediary between the Circle and bishops Grober of Freiberg and Preysing of Berlin. After the failure of the 1944 July Plot to assassinate Hitler, König was pursued by the Gestapo and sought refuge in a coal cellar, where he lived in hiding until the end of the war. König died shortly after the war from the effects of his time in hiding.
