Wolfgang Kaiser (born Leipzig 16 February 1924: executed Dresden 6 September 1952) was a member of Rainer Hildebrandt's "Struggle against Inhumanty" group (KgU / Kampfgruppe gegen Unmenschlichkeit) which campaigned against the one party dictatorship in the German Democratic Republic.
In the 1952 Hildebrandt conspiracy show trial, he was identified on 8 August as the "chief chemist" of the KgU and, on 9 August, condemned to death in the country's Supreme Court.
