Robert Herman Alfred de Foy (Geraardsbergen 23 March 1893 - Brussels 15 August 1960 ) was a Belgian magistrate, and head of the Belgian State Security Service, who served the Nazis during their occupation of Belgium. This period of his life has led to some considerable historic debate around de Foy's legacy, but in the post-war period returned to his pre-war position, decorated Grand Officer of the Order of Leopold II, and recognised as "Righteous" by the state of Israel.
