What is the name of stunning spell in Harry Potter?

The Stunning Spell, also known as the Stupefy Jinx, is a spell used to momentarily stun or knock out an opponent. The incantation for the spell is "Stupefy!" and when it is cast, a jet of red light shoots from the caster's wand, hitting the target and rendering them unconscious. The effects of the spell can be temporary, lasting for a few moments, or they can be more long-lasting, depending on the strength and focus of the caster.
