Werner Teske (24 April 1942 – 26 June 1981) was an East German Hauptmann (Captain) of the Ministry for State Security (Stasi) who was executed for "planned treason" in June 1981. Teske was a senior intelligence officer in the Stasi's economic espionage division when he was accused of plotting to defect to West Germany with sensitive information and embezzled money. Teske was found guilty of treasonous acts and sentenced to death, despite not meeting the requirements for East German law, and subsequently executed. Teske's sentence was posthumously overturned after German Reunification when it was deemed unlawful and two jurists from his trial were prosecuted.
