Jakobus Onnen (3 August 1906 – 12 August 1943) was a German schoolteacher and a member of the Nazi Schutzstaffel (SS) who served in a mobile killing unit during World War II. He was identified as the individual who appears as the executioner in the Holocaust photograph The Last Jew in Vinnitsa, which depicts a Nazi officer about to shoot a Jewish man at a mass grave in 1941, by the historian Jürgen Matthäus in 2025. Onnen was killed in action on the Eastern Front in 1943 and was never prosecuted for his crimes, remaining unidentified as a war criminal for decades after the war.
