Stephen Desberg is a Belgian writer of comics. In 2010, he was the 10th bestselling author of comics in France, with 412,000 copies of all his comics together sold that year.

Stephen Desberg was born in Brussels in 1954 as the third child of an American lawyer from Cleveland and a French mother who taught him French at the Sorbonne after the Liberation of Paris. They settled in Brussels when Stephen's father became responsible for the distribution of Metro-Goldwyn-Mayer films in Belgium, Luxemburg and the Netherlands. After finishing college two years late, he studied law at the Université Libre de Bruxelles, but didn't finish his studies.

His youth was mainly dominated by American movies, but he also enjoyed the weekly Spirou magazine with series like Buck Danny or the works of Raymond Macherot. He only discovered the authors who published in the main competitor Tintin magazine much later. He became a regular at the comics shop of Michel Deligne, who also republished classic comics and a fanzine. After Desberg published his first work here, Deligne introduced him to Maurice Tillieux, one of the major authors of Spirou at the time. At first, he offered some ideas and synopses to Tillieux for series like Jess Long and Tif et Tondu, but he eventually moved to full scenarios for Tif et Tondu, drawn by Will. He started working for a number of other Spirou authors, including Benn, Pierre Seron, Raymond Macherot and Eric Maltaite (the son of Will).

His first success came in 1980 with Billy the Cat, drawn by Stéphane Colman. He also created 421 with Eric Maltaite, in 1983 Arkel with Marc Hardy, and in 1988 Jimmy Tousseul with Daniel Desorgher. Despite all this, he was simultaneously but unsuccessfully trying to become a professional musician.
