Carl Vincent Krogmann (3 March 1889, in Hamburg – 14 March 1978, in Hamburg) was a German banker, industrialist and Nazi Party politician. He served as Mayor of Hamburg for the majority of the Nazi period of government. Early years Krogmann was born into one of Hamburg's old Huguenot and married Emerentia Krogmann, who was noted for her antisemitic views. He came from a leading shipping family and inherited one of the city's leading maritime concerns as a result. Krogmann was a founder member of the Freundeskreis der Wirtschaft, an influential group of far right industrialists established in 1932 by Wilhelm Keppler.

Initially mayor, he had been given the stronger title Regierender Bürgermeister following the dissolution of the Hamburg Parliament. However, as Kaufmann's power grew so Krogmann's status diminished so as by 1937 he had been demoted to the lesser title of First Councillor of the Municipal Authority. Despite his shaky status Krogmann, a devotee of the writings of Richard Wagner, Paul de Lagarde and Houston Stewart Chamberlain, was a staunch believer in Nazism, especially its antisemitic aspects and rigorously enforced anti-Jewish laws within Hamburg whilst publicly speaking in support of them elsewhere. He demonstrated this in particular in a speech he delivered to the Ostasiatischer Verein in 1935 in which he rounded on members of the business community who were critical of the racial policy of the Third Reich, whilst emphasising
