The Stunning Spell (Stupefy), also known as a Stunner or Stupefying Charm is a charm that renders a victim unconscious and halts moving objects. This spell is also commonly used in duels; it is quite useful if one's opponent is unconscious and unable to continue the duel and is a guaranteed victory for the caster.
It is unknown who invented the spell, and when. In 1995, Harry Potter learned this spell in preparation for the third task of the Triwizard Tournament. He practised it on Ron Weasley who complained about it not being easy to aim where you fall when you are stunned. Harry also taught this spell to Dumbledore's Army during the 1995-1996 school year, during one of the meetings. The spell was used numerous times during the Battle of the Department of Mysteries, by both the D.A. and the Order of the Phoenix; it was also used during many other battles of the Second Wizarding War, such as the Battle of the Astronomy Tower, the Battle of the Seven Potters, the Skirmish at Malfoy Manor, the 1998 Break-in of Gringotts Wizarding Bank, and the Battle of Hogwarts.
It may be assumed that this spell was also used frequently during the First Wizarding War as well, by the wizarding community at large.
If this spell is used by multiple wizards aiming at the same target, the damage it causes is increased; for example, Professor McGonagall had to be moved to St Mungo's after being hit with the spell by multiple Ministry of Magic employees in 1996, and Madam Pomfrey expressed surprise that it did not kill her. Dragons are able to shrug off a single Stunning Spell, but if multiple Stunning Spells are aimed at a dragon, they should work. It manifests itself as a jet of scarlet light.
Defence against stunning
- "The effects of the Stunning Spell may be counteracted by 'Rennervate', but will also wear off with time on their own. Another method of avoiding the spell is to deflect it with a Shield Charm."
- —Defence against the spell[src]
The effects of a Stunning Spell may be counteracted by Rennervate, but will also wear off with time. It can also be deflected by a Shield Charm. Species known to be naturally resistant to the spell include dragons, trolls, giants and half-giants. Rubeus Hagrid was unaffected by this spell when, in 1996, several Ministry of Magic employees attempted to remove him from Hogwarts grounds.

"Stupefy" comes from the English stupefy, which means "to stun" or "to amaze". It may also come from the Latin stupere, meaning "to be stunned".
Behind the scenes
- Another variation of the spell is Stupefy Duo.
- The Stunning Spell has been identified as a jet, a flash or a burst of red, blue, white or green light in the film adaptions.
- In the books, it is described as a "jet of red light," and appears as such at the beginning of the film adaptation of Harry Potter and the Goblet of Fire, when Ministry of Magic Officials apparate near the trio and attempt to stun them after the destruction of the Quidditch World Cup fair grounds. However, from the film adaptation of Harry Potter and the Order of the Phoenix on, it is shown as blue light that often just knocks people off their feet.
- Harry counters unidentified green curses cast by Death Eaters with the Stunning Spell, causing the spells to collide and explode in midair. If these green curses were Killing Curses, then this would indicate that Killing Curse can be parried if it collides with another spell.
- In the video game adaptation of Harry Potter and the Half-Blood Prince, Stupefy is shown as a ball of red light, but when cast by opponents, it is green, like the Killing Curse. Also at the end after Harry defeats Bellatrix Lestrange outside Hagrid's hut he casts Stupefy but instead of the red light it came out as a green ball of light.
- In Harry Potter and the Deathly Hallows, Hermione attempts to use a Stunning Spell on one of the enemy giants, but is prevented from doing so by Ron as it would "crush half the castle." However, it was Hermione herself who pointed out in Harry Potter and the Order of the Phoenix that Stunning Spells are almost completely ineffective against Giants, even when cast by multiple wizards.
- In LEGO Harry Potter: Years 1-4, it can be bought at Wiseacre's Wizarding Equipment in Diagon Alley.
- Flavius Belby tried to use this spell against a lethifold, however it had no effect as lethifolds can only be repelled by the Patronus Charm like with Dementors.
- In Harry Potter and the Deathly Hallows: Part 2, Hermione casts Stupefy at Blaise in the Room of Requirement instead of Gregory Goyle. This is due to Crabbe's part being replaced by Blaise and thus is Goyle is the one to conjure the Fiendfyre.
- It has been implied that Dobby does this to Wormtail in Harry Potter and the Deathly Hallows: Part 1. However, when Harry does this to Umbridge and Mafalda, they are instantly knocked out, while Wormtail stands for a few seconds, says "Ow" (hinting that the spell was quite painful) and collapses. This, as well as his unintended non-reappearance in Part 2, suggests that he may be dead, or that Dobby used a different spell to knock him out.
- Also in Deathly Hallows: Part 1, When Ron (disguised as Reginald Cattermole) hits Yaxley with a non-verbal Stunning Spell, it seems to strike his chest rather hard, causing him to groan in pain and leaving him incapacitated for several minutes before he catches up with the trio and attempts to stop their escape.
- In Deathly Hallows: Part 2, Voldemort casts Stupefy at Neville Longbottom out of anger, after Harry Potter seemingly came back to life. Neville was blown backward into the Great Hall, and remained unconscious until he woke to slay Nagini.
- In Harry Potter for Kinect Harry and Voldemort can use this spell against each other in the final battle during Voldemort's Last Stand as they engage in a normal duel.
