Philippe Labarthe, pseudonym Ylipe (9 January 1936 – 8 March 2003) was a French humorist, artist, and writer. He was born in Bordeaux and studied Fine Arts there before moving to Paris to work as a cartoonist, painter and aphorist. He signed his cartoons φlipe, using the Greek letter phi (φ) in place of the first three letters of his forename. Maurice Nadeau misread the Greek φ as a Latin y and the name Ylipe stuck.
