What Latin motto appears on the crest of Hogwarts in the Harry Potter series?

The Hogwarts crest motto in the Harry Potter series is Draco dormiens nunquam titillandus.

The Latin phrase translates as “Never tickle a sleeping dragon.” It functions as the motto of Hogwarts School of Witchcraft and Wizardry, the fictional boarding school attended by Harry Potter and many other characters.

Hogwarts is described as a secondary school in Scotland, enrolling magical children from about age eleven through eighteen. Its students are divided among four Houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin, each named for one of the school’s founders.

The motto’s playful warning suits the series’ combination of school tradition, medieval imagery, and magical danger. It is sometimes confused with the names of the four Houses or with Latin phrases used elsewhere in the wizarding world, but it belongs specifically to Hogwarts itself.
