All around the world, Richelieu (Richelieu ) is a rare predominantly male, but scarcely feminine forename. The first name Richelieu is characteristic of Philippines, where it is a rare male name, the Democratic Republic of the Congo, and Israel, where it is a rare dominantly girly, but uncommonly masculine name. In absolute terms, it is commonest in Philippines, the Democratic Republic of the Congo, and the United States. Likewise, Richelieu is the last name as well as the forename.
