The Swedish town of Vimmerby, Lindgren's hometown, has a theme park based on the Pippi Longstocking series of books. Scenes from the book are recreated at one-third scale, and actors roam the park dressed as Pippi and other characters.
The most popular children's festival in Slovenia, annually held in Velenje since 1990, is named Pika's Festival after Pippi Longstocking.
Swedish author Stieg Larsson, in writing his Millennium series, has stated that one of the main characters in the three novels, Lisbeth Salander was fashioned on a grown-up Pippi Longstocking. In the only interview he ever did about the series, Larsson stated that he based the character on what he imagined Pippi Longstocking might have been like as an adult.
Pippi appears on the obverse of the Swedish 20 kronor note. The note, released in October 2015, also features a portrait of Lindgren and a motif of Småland, Sweden, the province in which she grew up.
