List of Harry Potter translations

The Harry Potter series of fantasy novels by J. K. Rowling is one of the most translated series of all time, being available in 85 languages. This includes languages with fewer than a million speakers such as Basque, Greenlandic, and Welsh, as well as the Classical languages Latin and Ancient Greek. Additionally, regional adaptations of the books have been made to accommodate regional dialects such as the American English edition or the Valencian adaptation of Catalan.

For reasons of secrecy, translations were only allowed to begin after each book had been published in English, creating a lag of several months for readers of other languages. Impatient fans in many places simply bought the book in English instead. Harry Potter and the Order of the Phoenix became the first English language book to top France's best-seller list. In some cases, fans have created their own unofficial translations, either ahead of a licensed translation or when a licensed translation is unavailable.

Issues arising in the translation of Harry Potter include cultural references, riddles, anticipating future plot points, and Rowling's creative names for characters and other elements in the magical world which often involve word play and phonology.
