The Auschwitz trial began on November 24, 1947, in Kraków, when Poland's Supreme National Tribunal tried forty former staff of the Auschwitz concentration camps. The trials ended on December 22, 1947.

The Supreme National Tribunal was a war-crime tribunal active in communist-era Poland from 1946 to 1948. Its aims and purpose were defined by the State National Council in decrees of 22 January and 17 October 1946 and 11 April 1947. The new law was based on an earlier decree of 31 August 1944 issued by the new Soviet-imposed Polish regime, with jurisdiction over "fascist-Hitlerite criminals and traitors to the Polish nation". The Tribunal presided over seven high-profile cases involving a total of 49 individuals.
