Alexandre Adler (23 September 1950 – 18 July 2023) was a French historian, journalist and expert of contemporary geopolitics, the former USSR, and the Middle East. He was a Knight of the Legion of Honour (2002). A Maoist in his youth and then a member of the Communist Party (PCF), he shifted to the right at the end of the 1970s and later became close to U.S. neoconservatives, as did his wife Blandine Kriegel (daughter of the communist Resistant Maurice Kriegel-Valrimont). Adler was the counsellor of Roger Cukiermann, chairman of the Conseil Représentatif des Institutions juives de France (CRIF, Representative Council of Jewish Institutions of France).
