Horst Ludwig Georg Erich Wessel (9 October 1907 – 23 February 1930) was a Nazi Party (NSDAP) activist known for writing the lyrics to the "Horst-Wessel-Lied". His death in 1930 was used by the party for propaganda purposes.

Wessel first joined the German National People's Party (DNVP), but by 1926 was removed for being too extremist. He then joined the NSDAP, where he wrote songs for Nazi events. He rose to command several SA squads and districts. On 14 January 1930, he was shot in the head by two members of the Communist Party of Germany (KPD). Albrecht Höhler was arrested and charged with his murder. He was initially sentenced to six years in prison, but was executed after the Nazis came to power. Wessel's funeral was given wide attention in Berlin, with many of the Nazi elite in attendance. After his death, he became a major Nazi propaganda symbol. His name was used for several civilian and military purposes during the time of the Third Reich.
