Caroline Frédérique Bernardine Hamaekers (12 June 1836 – 24 October 1912) was a Belgian soprano prominent in the opera houses and demimonde of Paris from the mid-1850s through 1869. For a time she was the mistress of Napoleon III, but had several other lovers. In 1870 she returned to Belgium where she was a prima donna at the Théâtre Royal de la Monnaie until her retirement from the stage in 1884. Her last years in Brussels found her almost destitute. In a fit of despair she committed suicide at the age of 76.
