Harry Potter and the Order of the Phoenix has 38 chapters.
Published in 2003, it is the fifth and longest novel in J. K. Rowling’s Harry Potter series. The story follows Harry during his fifth year at Hogwarts, as the Ministry of Magic denies Voldemort’s return and appoints Dolores Umbridge to impose its policies at the school. The chapter structure carries Harry from his isolation at Privet Drive through the formation of Dumbledore’s Army and the battle at the Department of Mysteries.
The final chapter is titled “The Second War Begins,” reflecting the book’s turning point: Cornelius Fudge finally sees Voldemort and can no longer dismiss Harry and Dumbledore’s warnings. Readers sometimes confuse the novel’s chapter count with its length in pages. The original UK edition runs to 766 pages, but page counts vary by edition, formatting, language and printing. The 2007 film adaptation condenses this 38-chapter story into a 138-minute movie.
