Captain William Charles Bonaparte-Wyse (20 January 1826 – 3 December 1892) was an Irish soldier and poet.
Nicknamed lo felibre irlandés, he wrote in Provençal, was a friend of Frédéric Mistral, and became the only foreign member of the consistory of the Félibrige, the Provençal cultural association. His collection Li Parpaioun Blu (The Blue Butterflies) was published in 1868, with a foreword by Mistral. He created the Provençal dish of dried figs poached in whiskey.
He married in 1864, in London, Ellen Linzee Prout (1842–1925, niece of Servant of God Sister Elizabeth Prout), and they had four sons. He was the father of Permanent Secretary Andrew Nicholas Bonaparte-Wyse (1870–1940). His eldest son's godfather was Frédéric Mistral.
