Jean Passepartout is a fictional character in Jules Verne's novel Around the World in Eighty Days, published in 1873. He is the French valet of the novel's English main character, Phileas Fogg. His surname translates literally to "goes everywhere", but “passepartout” is also an idiom meaning "skeleton key" in French. It can also be understood as a play on the English word passport—or its French equivalent passeport.
