- "...although he could barely see out of it, he pointed his wand through the smashed window and started muttering incantations of great complexity. Harry heard a weird rushing noise, as though Flitwick had unleashed the power of the wind into the grounds."

Protego Horribilis is a stronger version of the Shield Charm which protects a very large area against highly Dark Magic. It causes anything within the ranges of Dark Magic to rebound off the shield.
Known uses
- This spell was cast by Charms Master Filius Flitwick to protect the boundaries of Hogwarts Castle from the Death Eater forces in the late hours of May 1, 1998, prior to the Battle of Hogwarts that started at midnight the next day.
Etymology
Latin Protego, "I protect", and Horribilis, "horrible , frightful, dreadful"; altogether the charm means "I protect against the horrible."
Behind the scenes
- In Harry Potter and the Deathly Hallows: Part 2, this spell is not used. However, the similarly named Protego Maxima is among the defences that are put up in the film.
