John Arne Sæterøy (born 16 May 1965), better known by the pen name Jason, is a Norwegian cartoonist, known for his sparse drawing style and silent, anthropomorphic animal characters.

Jason was born in Molde, and had his work published for the first time in 1981 in the Norwegian comics magazine KonK, to which he contributed several short stories during its lifespan.

Since 2007, Jason has been living in Montpellier, and[3] his recent graphic novels have been initially published in French.

Jason's work is usually drawn in a minimalist, clean style, influenced by Hergé's ligne claire.

[4] For example, Tell Me Something is inspired by Buster Keaton's movies,[6] Frankenstein's Monster and related characters appear in You Can't Get There From Here, and fictionalized versions of Ernest Hemingway and other writers are the protagonists of The Left Bank Gang.
