Hogwarts School of Witchcraft and Wizardry is a fictional boarding school of magic for students aged eleven to eighteen, and is the primary setting for the first six books in J. K. Rowling's Harry Potter series and serves as a major setting in the Wizarding World universe.

A boarding school is a school where pupils live within premises while being given formal instruction. The word "boarding" is used in the sense of "room and board", i.e. lodging and meals. As they have existed for many centuries, and now extend across many countries, their functioning, codes of conduct and ethos vary greatly. Children in boarding schools study and live during the school year with their fellow students and possibly teachers or administrators. Some boarding schools also have day students who attend the institution during the day and return home in the evenings.
