Jean Henri Gaston Giraud (French: [ʒiʁo]; 8 May 1938 – 10 March 2012) was a French artist, cartoonist, and writer who worked in the Franco-Belgian bandes dessinées (BD) tradition. Giraud garnered worldwide acclaim predominantly under the pseudonym Mœbius (/ˈmoʊbiəs/; French: [møbjys]) for his fantasy/science-fiction work, and to a slightly lesser extent as Gir (French: [ʒiʁ]), which he used for the Blueberry series and his other Western-themed work. Esteemed by Federico Fellini, Stan Lee, and Hayao Miyazaki, among others, he has been described as the most influential bande dessinée artist after Hergé.

His most famous body of work as Gir concerns the Blueberry series, created with writer Jean-Michel Charlier, featuring one of the first antiheroes in Western comics, and which is particularly valued in continental Europe. As Mœbius, he achieved worldwide renown (in this case in the English-speaking nations and Japan, as well – where his work as Gir had not done well), by creating a wide range of science-fiction and fantasy comics in a highly imaginative, surreal, almost abstract style. These works include Arzach and the Airtight Garage of Jerry Cornelius. He also collaborated with avant garde filmmaker Alejandro Jodorowsky for an unproduced adaptation of Dune and the comic-book series The Incal.

Mœbius also contributed storyboards and concept designs to several science-fiction and fantasy films, such as Alien, Tron, The Fifth Element, and The Abyss. Blueberry was adapted for the screen in 2004 by French director Jan Kounen.
