Geronimo Stilton is an Italian best-selling children's book series published by Edizioni Piemme of Milan, Italy, since 2000. Scholastic Corporation has published the English version of the series since February 2004. Although the series credits its title character as the author, the idea was originally thought of by Elisabetta Dami. On older novels, the copyright is issued to a pseudonym "Geronimo Stilton"; this was changed on newer books. The books are intended for readers in the 6–12-year-old age range.
In the series, the title character is a talking mouse who lives in New Mouse City on Mouse Island. A best-selling author, Geronimo Stilton works as a journalist and editor for the fictional newspaper The Rodent's Gazette.
He has a younger sister named Thea Stilton, a cousin named Trap Stilton, and a favorite little nephew, nine-year-old Benjamin Stilton. Geronimo is a nervous, mild-mannered mouse who would like nothing better than to live a quiet life, but he keeps getting involved in far-away adventures with Thea, Trap, and Benjamin, and sometimes Aunt Sweetfur. The books are written as though they are autobiographical adventure stories.
The series originated in Italy and has become the most popular children's book series in that country. The books have been translated into 35 languages.
Papercutz obtained the rights to publish English translations of the graphic novels of Geronimo Stilton. These retain some of the original names of the characters that were changed in the storybooks translated by Scholastic. For example, the English translations of the graphic novels by Papercutz continue to use the names "Patty Spring" and "Pandora", while the storybooks by Scholastic changed these names to Petunia Pretty Paws and Bugsy Wugsy, respectively.
As of November 2016, 18 English translations of the graphic novels have been published.
The characters of Geronimo Stilton also used their other names from the 2nd to the 6th novel.
