Frank Margerin (born 9 January 1952, in Paris) is a French author and illustrator of comics.
After secondary school, Margerin went to a school of applied art, where he met Denis Sire. He joined Sire's band, Los Crados, as a drummer. The band later became Dennis' Twist.
In 1975, while looking for work in publishing or illustrating, Margerin met Jean-Pierre Dionnet, who ordered his first comic strip, a four-page parodical science fiction story named "Simone et Léon", for the Métal Hurlant magazine. He later drew and wrote several other stories for the magazine. His first album, Frank Margerin présente..., which gathered his first works for Métal Hurlant, was published in 1978. These first stories often have elements of science fiction, to fit with the other strips of Métal Hurlant. After "Simone et Léon", he also wrote and drew several works for Rigolo, a short-lived magazine. He won his first prize in 1980 at the Lucca Comics & Games festival in Lucca.
