During the Dachau liberation reprisals, German SS troops were killed by U.S. soldiers and concentration camp prisoners at the Dachau concentration camp on April 29, 1945, during World War II. It is unclear how many SS guards were killed in the incident, but most estimates place the number killed at around 35–50.

During the liberation of the Dachau concentration camp on April 29, 1945, many of the remaining SS guards were killed in what is known as the Dachau liberation reprisals. Upon entering the camp and discovering the "Death Train"—wagons filled with thousands of emaciated corpses—U.S. soldiers from the 45th and 42nd Infantry Divisions were so overwhelmed by horror and rage that they summarily executed a number of guards who had surrendered. Estimates vary, but historical records suggest roughly 35 to 50 SS personnel were killed in these incidents, some by American troops and others by liberated prisoners. The remaining hundreds of guards were taken as prisoners of war. While an investigation into the conduct of the U.S. soldiers was launched by the Inspector General, General George S. Patton eventually dismissed all charges, citing the unprecedented and extreme psychological trauma the soldiers faced upon witnessing the atrocities of the Holocaust.
