Vladimir Dedijer (Serbian Cyrillic: Владимир Дедијер; 4 February 1914 – 30 November 1990) was a Yugoslav partisan fighter during World War II who became known as a politician, human rights activist, and historian.

His father, Jevto Dedijer, was a professor of geography at Belgrade University and his mother, Milica, was a social worker.

After Olga died in 1943, her widower married again the next year to Vera Križman, an actress and fellow Yugoslav Partisan.

In 1931, he attended the XX World Congress of the Young Men's Christian Association in Cleveland, Ohio in the United States.

As a journalist, he became a foreign correspondent in Poland, Denmark, Norway (1935), England (1935–1936), and Spain (1936) in the years before the outbreak of World War II.

[7] After the war, Dedijer served as a member of the Yugoslav delegation on 1946 Paris peace conference and in several sessions of United Nations General Assembly (1945–1952).

In response, Dedijer was expelled from the CPY, removed from his political offices, and dismissed from his teaching position in the History Department at the University of Belgrade.

Dedijer is known for his book, The Yugoslav Auschwitz and the Vatican: The Croatian Massacre of the Serbs During World War II, which was translated into several languages.

He wrote about the violent repression and genocide committed by Ustashe Catholics in Croatia against ethnicities and religions that they considered heretics.

[7] Dedijer wrote two important accounts of Yugoslav Partisan history: Diary and Tito, both of which have been published in English.

[12] Together with French philosopher and activist Jean-Paul Sartre, he chaired the Bertrand Russell International Tribunal on War Crimes, organized in 1966, in the role of the first vice-president.

The Tribunal was due to sit in Paris, but the French authorities refused to grant an entry visa to Dedijer.

The Tribunal dealt with the denial of the right of individuals to practice their chosen profession in West Germany because of their political convictions, after the government had issued a discriminatory decree against radicals at a time of great social unrest in the nation.
