Ferdinand Peroutka (6 February 1895 – 20 April 1978) was a Czech journalist and writer. A prominent political thinker and journalist during the First Czechoslovak Republic, Peroutka was persecuted by the Nazi regime for his democratic convictions and imprisoned at Buchenwald concentration camp. Following the 1948 coup by the Communist Party of Czechoslovakia, he emigrated to both the United Kingdom and, later, the United States.
