Gerhard Löwenthal (8 December 1922 in Berlin – 6 December 2002 in Wiesbaden) was a prominent German journalist, human rights activist and author. He presented the ZDF-Magazin, a news magazine of ZDF which highlighted human rights abuses in communist-ruled Eastern Europe, from 1969 to 1987. Löwenthal, who was known as a staunch anticommunist, was president of the Germany Foundation from 1977 to 1994.
He was Jewish and was deported to the Sachsenhausen concentration camp during Nazi rule. After the war, he chose to remain in his native country and went on to study medicine. He also worked as a reporter for RIAS, before he became one of the first students at the Free University of Berlin. He considered himself "a man of the center" ("ein Mann der Mitte") and lamented the ever increasing trend towards left in the West German political life, which made him look like an arch-conservative.
His father-in-law was CDU politician and minister Ernst Lemmer.
The Gerhard Löwenthal Prize, annually awarded by his widow Ingeborg Löwenthal, the conservative newspaper Junge Freiheit and the Foundation for Conservative Education and Research, is named in his honour.
He is buried at the Jewish cemetery at Heerstraße in Berlin.
