Guy Mortier (March 24, 1943) is a Belgian journalist, best known as former chief editor of the Flemish magazine Humo.
Mortier was chief editor of Humo from 1969 until 2003. He gave the magazine a humorous touch and spent a lot of attention to rock music. Mortier bears a physical resemblance to Frank Zappa (long black hair, moustache, goatee), which has been a running gag in Humo for decades. Unsurprisingly, Mortier himself is a huge Zappa fan. When asked to talk about his favorite musical artists for a radio show he said: "Some of my musical heroes would take too much explanation. Frank Zappa, for instance, who has meant a lot to me. I cannot explain that man's genius in less than a quarter of an hour." 
Marc Didden: "Right. One more question: Don't you find it to be annoying to be mistaken for Guy Mortier all the time?"
Frank Zappa: "Aahh, the toll of fame my friend, nothing you can do against that."
