Harry Potter and Leopard-Walk-Up-to-Dragon is the title (loosely translated into English) of an unauthorized book written and published in 2002. It was written and published in China, and it was seen as an attempt to profit from the worldwide popularity of the Harry Potter series of books. At that time the anticipation for the release of the fifth book in the series, Harry Potter and the Order of the Phoenix, had reached a fever pitch.

The book was quickly recognized as a fake, and the estate of J.K. Rowling (as well as publisher Warner Bros) took steps to stop its distribution. Nevertheless, copies of the book were briefly distributed around the world, including e-book copies traded on the Internet. When the actual novel Harry Potter and the Order of the Phoenix was released in 2003, interest in the unauthorized book quickly faded.

Readers who have given Harry Potter and Leopard-Walk-Up-to-Dragon even a cursory read quickly noted many errors and inconsistencies between the book's story and the official series written by Rowling. The story centers around a struggle between Harry and his classmates at the Hogwarts School of Witchcraft and Wizardry and a mysterious wizard.

Characters well-known to fans of Rowling's series make an appearance -- the Dursleys, Harry's friends Hermione Granger and Ron Weasley, and his archrival Draco Malfoy. (In a bizarre plot twist, Harry and Hermione become lovers in this story -- something that Rowling has suggested will never happen in the official series.) In several instances in the book, the master wizard Albus Dumbledore is referred to as Gandalf.

The cover of the book shows a dark-haired, bespectacled boy in black robes riding a satyr, battling a dragon.

In what is seen as a genuine homage to Rowling, the book includes a dedication to the owner of the house in Edinburgh, Scotland, where Rowling lives, and to the owner's 3-year-old granddaughter.

The identity of the anonymous author of the book has not been discovered, as of 2003.
