From Peppi Pitkätossu, a character in a children's book by Astrid Lindgren, known in English as Pippi Longstocking. Translated as Peppi by Laila Järvinen in 1946, since Pippi would have negative meanings in Finnish (see pipi, pippeli).
The name may be explained as a short form of Peppina, an Italian diminutive of Giuseppina (“Josephine”).
