Alexandrine Bonaparte, Princess of Canino and Musignano (née Alexandrine de Bleschamp; 23 February 1778 – 12 July 1855) was a French aristocrat and by marriage member of the French Imperial family.

Marie Laurence Charlotte Louise Alexandrine was born as the only child of Charles Joseph Jacob de Bleschamp (1747–1823) and his wife, Marie Philiberte Jeanne Louise Bouvet (1759–1838).

Her maternal grandparents were Jean Charles Bouvet and his wife, Marie Gaspardine Grimod de Verneuil (1738–1804).

Alexandrine was already a widow when she became the second wife of Lucien Bonaparte, a younger brother of Napoleon I of France, in 1803.
