Largo Winch is a Belgian comic book series by Philippe Francq and Jean Van Hamme, published by Dupuis.
The principal character is Largo Winch whose birth name is Largo Winczlav. Other important characters include Nerio Winch (his adoptive father), senior Group W executives John D. Sullivan and Dwight E. Cochrane, and his friend Simon Ovronnaz.
Largo Winch started as a series of novels by Jean Van Hamme in the late 1970s, but stopped due to a lack of success and the huge amount of work Van Hamme had in the meantime with his comic books (e.g. Thorgal). When artist Philippe Francq wanted to start a series with Van Hamme, he revived his old hero, and reworked the novels into the first albums of the comic series. Later, new stories followed.
