Ib Mossin (3 July 1933 – 17 December 2004) was a Danish actor, singer and director best known for his role as heartthrob Peter of the hugely popular Far til Fire film series.

He had his breakthrough as the apprentice Egon in 1953's Farlig Ungdom (Dangerous Youth), a stark drama about the crime scene in Copenhagen among adolescents.

When his stepfather died in 1951 he moved to Copenhagen where he studied acting under Danish actor Ejnar Juhl.

At the peak of his career he received 150 fan letters each day, which was considered a great accomplishment in Denmark at the time.

Even though he usually played one of the good guys in his starring films, he took part in the Danish hit series Matador about Denmark during World War II in the role as a Nazi, proving his versatility as an actor.
