Count Raoul du Bisson (11 January 1812 – 27 February 1890) was a French aristocrat, adventurer and agent provocateur.

He belonged to a Norman family ennobled by Louis XVIII and was a relative of Henri Conneau, a personal friend and physician of Napoleon III.

[1] In 1863, Du Bisson recruited a band of directionless Europeans in the cafés of Egypt and marched them down to Khartoum, where he pronounced it his intention to establish a colony for the production of cotton.

[1] In Khartoum, Du Bisson made numerous demands on the governor-general, Musa Paşa Hamdi, who eventually declared him persona non grata.

[1] According to yet others, he was the leader of the republican Central Committee of the Twenty Arrondissements and boastfully claimed to have been a Carlist in Spain, a Legitimist under the Second Empire, and a general of King Ferdinand II of the Two Sicilies.
