Which Harry Potter character is J.K. Rowling's main protagonist?

Harry Potter is the main protagonist of J.K. Rowling’s Harry Potter novel series.

Harry is introduced as an orphan living with his aunt, uncle, and cousin. On his eleventh birthday, he learns that he is a wizard and is invited to attend Hogwarts School of Witchcraft and Wizardry. The seven novels follow his education, friendships, moral choices, and confrontation with Lord Voldemort.

Ron Weasley and Hermione Granger are Harry’s closest friends and essential members of the central trio, but the narrative is primarily organized around Harry’s experiences. The books are generally told through a third-person limited viewpoint that closely follows what Harry knows and perceives.

Harry’s lightning-shaped scar and survival of Voldemort’s attack make him famous in the wizarding world before he understands his own history. His development from a neglected child into a responsible young adult forms the series’ emotional backbone.
