Charles Lucien Jules Laurent Bonaparte (May 24, 1803 – July 29, 1857) was a French naturalist and ornithologist. He was the son of Lucien Bonaparte and nephew of Emperor Napoleon.

Bonaparte was raised in Italy and, after his marriage to his cousin Zenaida on June 29, 1822 in Brussels, travelled to the United States. Before leaving Italy he had already discovered a warbler new to science, the Moustached Warbler, and on the voyage he collected specimens of a new storm-petrel. On arrival in the United States he presented a paper on this new bird, which was later named after Alexander Wilson.

Bonaparte then set about updating Wilson's American Ornithology, and the revised edition was published between 1825 and 1833. In 1824 Bonaparte tried to get the then unknown John James Audubon accepted by the Academy of Natural Sciences, but this was opposed by the ornithologist George Ord.

At the end of 1826 Bonaparte and his family returned to Europe. He visited Germany, where he met Philipp Jakob Cretzschmar, and England, where he met John Edward Gray at the British Museum, and renewed his acquaintance with Audubon. In 1828 the family settled in Rome. Between 1832 and 1841 Bonaparte published his work on the animals of Italy, Iconografia della Fauna Italica. He was exiled in 1849 for his involvement in the pro-nationalist movement, and died in Paris.
