What was the first Harry Potter book written by J.K. Rowling?

Harry Potter and the Philosopher’s Stone was the first Harry Potter book written by J.K. Rowling. It introduces Harry, Hogwarts School of Witchcraft and Wizardry, Ron Weasley, Hermione Granger, and the central conflict with Lord Voldemort.

The manuscript was completed after years of drafting and was accepted by Bloomsbury in the United Kingdom. The novel launched the seven-book series and established the core setting, magical rules, friendships, and history that later volumes expanded.

The British title uses “Philosopher’s Stone,” referring to the legendary substance associated with alchemy. In the United States, the book was published as Harry Potter and the Sorcerer’s Stone, so readers may encounter two titles for the same story.

The book’s international success led to translations, awards, audiobooks, merchandise, and a film adaptation. Its opening installment remains the starting point for the fictional chronology of Harry’s education at Hogwarts.
