Nils Holgerssons underbara resa genom Sverige (English: The Wonderful Adventures of Nils) is a work of fiction by the Swedish author Selma Lagerlöf. It was published in two books, part 1 (English: The Wonderful Adventures of Nils) in 1906 and part 2 (English: Further Adventures of Nils) in 1907. These two are usually combined into a single book called The Wonderful Adventures of Nils, although that name could also describe the first book only.
