Elisabeth Félix (21 February 1821 – 3 January 1858), better known only as Mademoiselle Rachel, was a French actress. She became a prominent figure in French society, and was the mistress of, among others, Napoleon III, Prince Napoléon, 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.
