Else Peerenboom-Missong (born Else Peerenboom; 13 October 1893 – 31 August 1958) was a German economist who became a politician (Catholic Centre Party, CDU). Between 1930 and 1933 she served as a member of the Reichstag (German parliament). She withdrew from politics during the twelve Nazi years, but in 1933 had spoken out personally to the Vatican diplomat, Cardinal Pacelli (later Pope Pius XII), in condemnation of the Concordat between the Holy See and the German Nazi State. This may have been one of various reasons why she was kept under close Gestapo surveillance. In the wake of the assassination attempt against Hitler in July 1944 she was one of those arrested and briefly detained in the context of what came to be known as Aktion Gitter. After the war she contributed significantly to the establishment of the CDU (party) in the Rhineland region.
