Rubeus Hagrid is a fictional character in the Harry Potter book series written by J. K. Rowling. Hagrid is introduced in Harry Potter and the Philosopher's Stone as a half-giant and half man who is the gamekeeper and Keeper of Keys and Grounds of Hogwarts, the primary setting for the first six novels. In the third novel Harry Potter and the Prisoner of Azkaban, Hagrid is promoted to Care of Magical Creatures teacher, and later becomes a member of the Order of the Phoenix.

Hagrid was among the characters that Rowling says she created "the very first day". She has explained the Источник of his name as "another old English word, meaning — if Ты were hagrid — it’s a dialect word — you’d had a bad night. Hagrid is a big drinker — he has a lot of bad nights." In her Статья "Harry’s Fame", Rosemary Goring notes the Forest of Dean is an influence on Rowling’s work, and Hagrid is the only character that is "directly drawn from the Forest of Dean". According to Goring, Hagrid’s "dropped word-endings are a Chepstow speciality." She also notes that Hagrid is physically "modeled on the Welsh chapter of Hells Ангелы who’d swoop down on the town and hog the bar, 'huge mountains of leather and hair".

The character of Hagrid and conversations between him, Harry Potter, Ron Weasley and Hermione Granger in his hut are expository through the series, due to the fact that the trio frequently discover things about Albus Dumbledore and Hogwarts by talking with Hagrid, as he has a habit of letting slip bits of information. He was also one of the first characters to imply that the idea of thinking of wizards as "pure-bloods" and "half-bloods" is a dated concept.

Rowling has stated in an interview that Hagrid was in Gryffindor house during his time as a student. When he comes into possession of an acromantula, he is expelled from Hogwarts as his pet is supposed to be the "monster of Slytherin". However, persuaded by Dumbledore (who at the time was Transfiguration teacher), Headmaster Armando Dippet agrees to train Hagrid as gamekeeper, allowing the boy to remain at Hogwarts. By the time Harry attends Hogwarts, Hagrid is also the Keeper of Keys and Grounds: the former, according to Rowling, means "that he will let Ты in and out of Hogwarts." Part of his job includes leading the first years across the lake in boats, upon their initial arrival at Hogwarts.
When discussing the killing off of characters in her books, Rowling сказал(-а) that she always knew she was "working towards the point where Hagrid carried Harry out alive - but supposedly dead - out of the forest". She сказал(-а) had planned from very early on that Harry would walk to his death accompanied by the 'ghosts', and that "he would emerge in Hagrid's arms". In her own words, "that's what always kept Hagrid safe". She сказал(-а) "Hagrid would have been a natural to kill in some ways", but that the mental image of this moment - a big fatherly Hagrid carrying the limp Harry in his arms - was so strong it decided his fate. She also liked the circular notion of Hagrid both bringing Harry into the world, and then bringing him back from the dead.
