The Republican Federation (French: Fédération républicaine, FR) was the largest conservative party during the French Third Republic, gathering together the progressive Orléanists rallied to the Republic. Founded in November 1903, the party competed with the more secular and centrist Alliance démocratique (Democratic Alliance). Later, most deputies of the Fédération républicaine and of Action libérale (which included Catholics rallied to the Republic) joined the Entente républicaine démocratique right-wing parliamentary group.
