Gustave Cunéo d'Ornano (15 November 1845 – 17 May 1906) was a French lawyer, journalist and politician who was a Bonapartist deputy for the department of Charente for thirty years. He represented the rural constituency of Cognac, and often supported the distillers in parliament. Although he supported democracy, he was in favour of plebiscites and opposed the republicans of the French Third Republic for most of his career. He took every opportunity to speak out against the government in the chamber of deputies. At one point an article he had written led to a duel with another deputy.
