The Adventures of Jo, Zette and Jocko is a Franco-Belgian comics series created by Hergé, the writer-artist best known for The Adventures of Tintin. The heroes of the series are two young children, brother and sister Jo and Zette Legrand, and their pet chimpanzee Jocko, plus their parents, Mr Legrand, Jo and Zette’s father, aerospace engineer and designer, and Mrs Legrand, Jo and Zette’s mother, housewife and Mr Legrand’s wife.

Bandes dessinées, abbreviated BDs and also referred to as Franco-Belgian comics, are comics that are usually originally in French and created for readership in France and Belgium. These countries have a long tradition in comics, separate from that of English-language comics. Belgium is a mostly bilingual country, and comics originally in Dutch are culturally a part of the world of bandes dessinées, even if the translation from French to Dutch far outweighs the other direction.
