Martin Sandberger (17 August 1911 – 30 March 2010) was an SS Standartenführer (Colonel) and commander of Sonderkommando 1a of the Einsatzgruppe, as well as commander of the Sicherheitspolizei and SD in Estonia. He played an important role in the mass murder of the Jews in the Baltic states. He was also responsible for the arrest of Jews in Italy and their deportation to Auschwitz concentration camp. Sandberger was the second-highest official of Einsatzgruppe A to be tried and convicted.

Martin Sandberger was born in Charlottenburg, Berlin as a son of a director of IG Farben. Sandberger studied law at the Universities of München, Köln, Freiburg and Tübingen. At the age of 20 he joined the NSDAP and the SA. From 1932 - 1933 Sandberger was a Nazi student activist and student leader in Tübingen. On 8 March 1933 Sandberger and fellow student Erich Ehrlinger raised the Nazi flag in front of the main building at the University of Tübingen. (Like Sandberger, Ehrlinger would take charge of an Einsatzkommando in 1941, and in so doing, commit thousands of murders.)
