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