The Hostages Trial was held from 8 July 1947 until 19 February 1948 and was the seventh of the twelve trials for war crimes that United States authorities held in their occupation zone in Germany in Nuremberg after the end of World War II. These twelve trials were all held before US military courts, not before the International Military Tribunal, but took place in the same rooms at the Palace of Justice. The twelve US trials are collectively known as the "Subsequent Nuremberg Trials" or, more formally, as the "Trials of War Criminals before the Nuremberg Military Tribunals" (NMT).

The subsequent Nuremberg trials were twelve military tribunals for war crimes committed by the leaders of Nazi Germany (1933–1945). The Nuremberg Military Tribunals occurred after the Nuremberg trials, held by the International Military Tribunal, which concluded in October 1946. The subsequent Nuremberg trials were held by U.S. military courts and dealt with the cases of crimes against humanity committed by the business community of Nazi Germany, specifically the crimes of using slave labor and plundering occupied countries, and the war-crime cases of Wehrmacht officers who committed atrocities against Allied prisoners of war, partisans, and guerrillas.
