What is the name of Harry's best male friend?

Harry Potter's best male friend is Ron Weasley. Ron becomes Harry's closest male companion after they meet on the Hogwarts Express before their first year at school.

Ron comes from the Weasley family, a large wizarding family known for its red hair, strong loyalty and opposition to pure-blood prejudice. He is the sixth son of Arthur and Molly Weasley and grows up alongside several older brothers and his younger sister, Ginny. Unlike Harry, Ron is not famous, but his knowledge of wizarding customs helps Harry understand the magical world.

Ron, Harry and Hermione Granger form the central friendship trio of the series. Ron contributes courage, humour and practical knowledge, although he sometimes struggles with jealousy and feelings of being overshadowed. He also becomes a talented chess player, a skill that helps the trio pass one of the protections surrounding the Philosopher's Stone.

Neville Longbottom and Seamus Finnigan are also Harry's classmates and allies, but neither is presented as his best male friend. Draco Malfoy is Harry's rival rather than his friend.
