Lucien Louis Joseph Napoléon Bonaparte, 4th Prince of Canino and Musignano (15 November 1828 – 19 November 1895), was a French cardinal and member of the House of Bonaparte.
His paternal grandparents were Lucien Bonaparte and his second wife, Alexandrine de Bleschamp.
His maternal grandparents were Joseph Bonaparte and Julie Clary.
He was ordained to the priesthood on 13 December 1856 by Pope Pius IX, giving up his Italian title.
In 1879, he was given the additional title of Cardinal Priest of S. Lorenzo in Lucina, as in this year Napoleon III's progeny had died out, while cardinal Lucien was the most genealogically senior member of the Bonaparte family (but born in a not-dynastic branch of the family, for the marriage of his grandparents).
