Gabriele Kröcher-Tiedemann (1951–1995) was a West German political terrorist associated with Movement 2 June (J2M) and the Second Generation Red Army Faction. She was the wife of the J2M terrorist Norbert Kröcher. Her nom de guerre was "Nada".
Kröcher-Tiedemann was born in Ziegendorf in Mecklenburg, Germany on 18 May 1951. She studied at a high school in Bielefeld before moving to Berlin to study politics and sociology. At that time she was associated with communes in Berlin and was opposed to Americans occupying Germany after World War II.
It is not clear at what point Kröcher-Tiedemann went underground, but in 1973 she shot a policeman in a Buchen carpark after he tried to arrest her for stealing number plates. She was subsequently arrested and was sentenced to eight years in prison.
However as a result of the Peter Lorenz kidnapping, she was freed two years later in 1975 and flown to Yemen.
On 21 December 1975 she participated with the international terrorist "Carlos the Jackal" on a raid of the OPEC headquarters in Vienna.
