What is the name of the Hogwarts gamekeeper?

The Hogwarts gamekeeper is Rubeus Hagrid. He is introduced in Harry Potter and the Philosopher’s Stone as the half-giant responsible for the school grounds and many of its dangerous creatures.

Hagrid’s role is broader than simply caring for plants and animals. He is also Hogwarts’ Keeper of Keys and Grounds, a position that includes helping newcomers enter the castle grounds. He guides first-year students across the lake in boats and lives in a hut at the edge of the Forbidden Forest.

Hagrid had been a Hogwarts student during Tom Riddle’s school years, but he was expelled after being blamed for opening the Chamber of Secrets. The real culprit was Riddle, later known as Voldemort. Hagrid was allowed to remain at Hogwarts and trained as gamekeeper.

Later, Hagrid becomes the Care of Magical Creatures teacher. That job leads to memorable lessons involving Buckbeak, hippogriffs, and other beasts, but it does not replace his long-standing work as gamekeeper. Argus Filch is the caretaker, a different Hogwarts position.
