Sophie Dawes, Baronne de Feuchères (c. 1795-1840), was an English-born "adventuress" best known as a mistress of Louis Henry II, Prince of Condé.

She was born at St Helens, Isle of Wight, the daughter of a alcoholic fisherman named Dawes. She grew up in the workhouse, went up to London as a servant, and became the mistress of the duc de Bourbon, afterwards Prince of Condé.

She was ambitious, and he had her well educated not only in modern languages but, as her exercise books still extant show, in Greek and Latin. He took her to Paris and, to prevent scandal and to qualify her to be received at court, had her married in 1818 to Adrien Victor de Feuchères , a major in the Royal Guards . The prince provided her dowry, made her husband his aide-de-camp and a baron. The baroness, pretty and clever, became a person of consequence at the court of Louis XVIII.

De Feuchères, however, finally discovered the relations between his wife and Condé, whom he had been assured was her father, left her - he obtained a legal separation in 1827 - and told the king, who thereupon forbade her appearance at court. Thanks to her influence, however, Condé was induced in 1829 to sign a will bequeathing about ten million francs to her, and the rest of his estate - more than sixty-six millions - to the duc d'Aumale , fourth son of Louis Philippe.

Again she was in high favor. Charles X received her at court, Talleyrand visited her, her niece married a marquis and her nephew was made a baron. Condé, wearied by his mistress's importunities, and but half pleased by the advances made him by the government of July, had made up his mind to leave France secretly. When on 27 August 1830 he was found hanging dead from his window, the baroness was suspected and an inquiry was held, but the evidence of death being the result of any crime appearing insufficient, she was not prosecuted. Hated as she was alike by legitimatists and republicans, life in Paris was no longer agreeable for her, and she returned to London, where she died in December 1840.
