Hermione Granger’s middle name in J.K. Rowling’s Harry Potter series is Jean.
Her full name is Hermione Jean Granger. Hermione is one of the central characters in the books and becomes Harry Potter’s close friend after meeting him and Ron Weasley on the Hogwarts Express. She is portrayed as exceptionally studious, resourceful and committed to helping others.
The name appears in the series’ wider canon rather than being a major plot point in the early novels. Rowling later clarified Hermione’s full name, and the character’s daughter, Rose Granger-Weasley, is named in the later stage story Harry Potter and the Cursed Child.
Hermione’s surname is sometimes confused with the names of actresses or other characters associated with the franchise. In the fictional story, she is born to Muggle parents who work as dentists. Her intelligence and knowledge of magic repeatedly help the trio solve problems that cannot be settled by courage alone.
