"The guard was confused. He stared down at the thin, golden Probe and then at his companion, who said in a slightly dazed voice, 'Yeah, you've just checked them, Marius."
—The Gringotts guards, bewitched by Harry Potter with this charm[src]

The Confundus Charm[5] (Confundo)[1] was a charm which confused and misdirected the target.[1] It worked on living and inanimate things, as long as the target had a mind to be confused.[5] There were varying degrees of confusion that could be caused by the spell, ranging from becoming unaware of the current situation, forgetting important information, or becoming particularly impressionable.[2]


The spell took a degree of skill to cast, as Severus Snape, a very powerful wizard who could flawlessly perform Nonverbal spell casting, had to give such considerable focus with it that he had to "frown in concentration."[6]

Cormac McLaggen being Confunded during Quidditch tryouts

Someone who had been affected by this charm was said to have been "Confunded." Immediately after the spell had been cast; the Confunded person would shudder when the spell hit them. It would cause any of varying degrees of confusion, from a simple trick[7] to making a person believe that they had come up with a complex plan when said plan was given to them by the caster.[6]

Not only did the spell work on living creatures, but it also was able to affect sentient objects, as demonstrated when Barty Crouch Junior Confunded the Goblet of Fire, though this was noted to be a difficult task, as the Goblet itself was a powerful magical artefact.[5]


During the 1989–1990 school year at Hogwarts School of Witchcraft and Wizardry, Professor Filius Flitwick taught this charm to fifth year students in Charms class, in preparation for their upcoming Ordinary Wizarding Levels.[8]

Known practitioners


Confundus, as well as the incantation Confundo, are derived from the Latin verb cōnfundere (cōnfundō - cōnfundere - cōnfūdī - cōnfūsum), meaning "to confuse, to perplex."

Behind the scenes

  • In the films and video games, the incantation for this charm is Confundus, and not Confundo as it should be.
  • Professor Severus Snape theorised to Minister Cornelius Fudge, and tried unsuccessfully to convince Albus Dumbledore into agreeing, that Sirius Black could have cursed Harry Potter and Hermione Granger with this charm; however, this was incorrect, as Black was actually telling the truth. This, however, could merely have been a cover-up to attempt to protect Harry due to his lasting love for his mother, and the reason he did the same for Hermione and Ron may have been that it would seem odd if only Harry was supposedly Confunded when all three of them attacked him.
  • Ronald Weasley used this spell to trick his Driving Examiner into letting him pass his driving test, which may have constituted a breach of the International Statute of Secrecy, but it is unknown if Ron faced any repercussions about it. It is possible that it was not considered a breach if no one noticed that magic was used.
