Serge Chapleau (French: [ʃaplo]; born 5 December 1945 in Montreal) is a Canadian political cartoonist.

Born in Montreal, Quebec, the youngest in a family of seven children, Chapleau grew up in a blue collar neighbourhood in Montréal, where his childhood kingdom was the back alley of rue Drolet.

After a return to Le Devoir in 1991, he became a cartoonist at La Presse in 1996, a post that he continues to occupy.

He and fellow Montreal cartoonist Terry Mosher were the subject of a 2003 documentary film, Nothing Scared, directed by Garry Beitel.

[2] Chapleau suffers from Dupuytren's contracture, a hand disease in which the formation of scar tissue under the skin of the palm causes fingers to curl inward and lose the motion of the tendons' ability to grip.
