Bosse-de-Nage is an American black metal/screamo band, formed in San Francisco, California.
The band's name is taken from Alfred Jarry's novel Exploits and Opinions of Dr. Faustroll, Pataphysician, in which it is the name of a monkey. Later in the novel, the narrator wonders whether the monkey ever existed, or whether it was merely a hallucination. The name translates from French roughly as "Bump Swimming".
