Elisabeth Félix, better known only as Mademoiselle Rachel (21 February 1821 – 3 January 1858), was a French actress.
She became a prominent figure in French society, and was the mistress of, among others, Napoleon III, Napoléon Joseph Charles Paul Bonaparte and Alexandre Colonna-Walewski, the illegitimate son of Napoleon I.
Efforts by newspapers to publish pictures of her on her deathbed led to the introduction of privacy rights into French law.
