Ligne claire, literally meaning the clear line, is a style of drawing pioneered by Hergé (creator of Tintin). The name was coined by Joost Swarte in 1977. It is a style of drawing which uses clear strong lines, strong colours and a combination of cartoonish characters against a realistic background. The use of shadows is sparse and all elements of a panel are delineated with clear black lines.

Hergé started out drawing in a much looser, rougher style which was influenced partially by the great American comic strip artists of the late 1920s and 1930s. It was only after World War II that his drawing style evolved into ligne claire.

Much of the "Brussels school" started to use this style, notably Edgar P. Jacobs, Bob DeMoor and Jacques Martin, many of which also worked for Tintin magazine .

The Ligne claire style achieved its highest popularity in the 1950s, but its influence started to wane in the 1960s and was seen as oldfashioned by the new generation of comic book artists.

In the late 1970s however it experienced a resurgence of interest, largely due to Dutch artists like Joost Swarte and Theo van den Boogaart , who had come up through the Dutch underground comics scene, as well as the French artist Jacques Tardi.

Contemporary use of the ligne claire is often ironic. For example, van de Boogaart used the simple, clear style to set up a conflict with the amorality of his characters, while Tardi used it in his Adèle Blanc-sec series to create a nostalgic atmosphere which is then ruthlessly undercut by the story.
