Rénald Luzier (born 7 January 1972),[1] known by his pen name Luz, is a French cartoonist.

[2] Luz has contributed to a number of publications including La Grosse Bertha, Les Inrockuptibles, Magic, Ferraille, L'Écho des Savanes, and Fluide Glacial.

He was awarded the Prix Tournesol at the Angoulême International Comics Festival in 2003 for his work Cambouis, a collection of his own fanzine that was published by L'Association in 2002.

Luz narrowly missed becoming a victim of the Charlie Hebdo shooting (on his birthday) because he was late for work[3] and turned up just in time to see the perpetrators fleeing.

In 2018, he published Indélébiles, a graphic novel about his 23 years experience at Charlie Hebdo.
