The Vrba–Wetzler report is one of three documents that comprise what is known as the Auschwitz Protocols, otherwise known as the Auschwitz Report or the Auschwitz notebook. It is a 33-page eye-witness account of the Auschwitz concentration camp in German-occupied Poland during the Holocaust.

The Hungarian biologist George Klein saved his life by fleeing, rather than boarding a Holocaust train, after he read the Vrba–Wetzler report as a teenager.
The Auschwitz Protocols, also known as the Auschwitz Reports, and originally published as The Extermination Camps of Auschwitz and Birkenau, is a collection of three eyewitness accounts from 1943–1944 about the mass murder that was taking place inside the Auschwitz concentration camp in German-occupied Poland during the Second World War. The eyewitness accounts are individually known as the Vrba–Wetzler report, Polish Major's report, and Rosin-Mordowicz report.
