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 and 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.

Translation process For an authorised translation, the publisher must first negotiate and sign a contract with Rowling's agents, The Blair Partnership. The publishers select translators locally.

So as to prevent plots being leaked, translators were not granted access to the books before their official release date in English; hence, translation could start only after the English editions had been published, creating a lag of several months before the translations were made available. This necessary delay has boosted the sales of English language editions of the books to impatient fans, in countries where English is not the first language. Such was the clamour to read the fifth book that its English edition became the first English-language book ever to top the bookseller list in France. In Italy, impatient Potter fans organised "Operation Feather", deluging the publisher Salani with feathers (reminiscent of Hogwarts' messenger owls) to demand expedited publication for the Italian translation of the seventh and final book in the series. This has also caused unauthorised translations and fake versions of the books to appear in many countries.

The high profile and demand for a high-quality local translation means that a great deal of care is often taken in the task. In some countries, such as Italy, the first book was revised by the publishers and issued in an updated edition in response to readers who complained about the quality of the first translation. In countries such as China and Portugal, the translation is conducted by a group of translators working together to save time. Some of the translators hired to work on the books were well known before their work on Harry Potter, such as Viktor Golyshev, who oversaw the Russian translation of the series' fifth book. Golyshev was renowned for his translations of William Faulkner and George Orwell, and was known to snub the Harry Potter books in interviews and refer to them as inferior literature. The Turkish translation of books two to five was undertaken by Sevin Okyay, a popular literary critic and cultural commentator.

In 2017, Bloomsbury celebrated the series' 20th anniversary with an announcement that it had been officially translated into 79 languages. Since 2017, Bloomsbury has published or licensed translations into Scots, Hawaiian, Belarusian, Kazakh, Yiddish, and Māori.

Some translations, such as those to the dead Latin and Ancient Greek languages, were done as academic exercises, to stimulate interest in the languages and to provide students of those languages with modern reading texts. The Ancient Greek version, according to the translator, is the longest text written in Ancient Greek since the novels of Heliodorus of Emesa in the 3rd century AD, and took about a year to complete.

List of translations by language The original British English versions of the book were published in the United Kingdom by Bloomsbury. Note that in some countries, such as Spain and India, the series has been translated into several local languages; sometimes the book has been translated into two dialects of the same language in two countries (for example, separate Portuguese versions for Brazil and Portugal).
