Arthur Annesley Ronald Firbank (January 17, 1886 – May 21, 1926) was an English novelist. He was educated at Cambridge. The son of a wealthy family, he dedicated himself to traveling through France, Italy, the Caribbean, North Africa and also Spain, where his guide was Hoyos and Vinent. Drinking ended up ruining his precarious health, hastening his early death.

He is one of the most unusual English writers of the twentieth century. His novels, extremely artificial, are authentic works of art in which fantastic humour, homosexual sensibility and "fin de siècle" scepticism prevail. Among them are Capricho, Valmouth, The Artificial Princess and Around the Eccentricities of Cardinal Pirelli. Luis Cernuda claimed that, in his eccentric way, Firbank tried to renew the novel as much as Proust and Joyce.
