Charles Guillaume Frédéric Boson de Talleyrand-Périgord (16 May 1832 – 21 February 1910), prince of Sagan (from 1845), duke of Sagan and duke of Talleyrand (from 1898) was a famous French dandy, and the grandson of Dorothea von Biron.
He was the son of Napoléon Louis, III. duc de Talleyrand-Périgord (1811-1898) and Anne Louise Charlotte Alix de Montmorency (1810-1858).

After his death, his titles passed to his son, Hélie de Talleyrand-Périgord, Duke of Sagan.[3]
