Alexandrine de Bleschamp was a French noblewoman. She was already the widow of the banker Hippolyte Jouberthon (having born him one child, Anna, in 1799), and thus known as "Madame Jouberthon", when she became the second wife of Lucien Bonaparte. She and her second husband had nine children, including:
- Charles Lucien Bonaparte (1803–1857), naturalist and ornithologist
- Louis Lucien Bonaparte (1813–1891).
- Pierre Napoleon Bonaparte (1815–1881).
