J.K. Rowling’s Harry Potter and the Order of the Phoenix contains 38 chapters.
Published in 2003, Harry Potter and the Order of the Phoenix is the fifth novel in the original Harry Potter series. It is also the longest book in the series by word count in its standard English edition, making its chapter total a useful bibliographic detail.
The story follows Harry’s fifth year at Hogwarts as the Ministry of Magic denies Voldemort’s return and limits the school’s teaching. Dolores Umbridge becomes Hogwarts’ High Inquisitor and later High Headmistress, while Harry forms Dumbledore’s Army to teach practical defensive magic.
Chapter counts can seem confusing because editions may differ in typography, page size, or supplementary material. The standard novel’s narrative is organized into 38 numbered chapters. The book concludes with the battle in the Department of Mysteries and the Ministry’s public recognition that Voldemort has returned.
