"The raven continued to open and close its sharp beak, but no sound came out."
— Description of the Silencing Charm[src]

The Silencing Charm (Silencio) was a charm that rendered the victim temporarily mute. Working on both beasts and beings, it was immensely difficult to perform, more so on ravens than frogs. If performed incorrectly, the target would swell up to an immense size and begin making deafening sounds.[1]


The song of the Fwooper would drive the listener insane, so wizarding law dictated that fwoopers must be sold with silencing charms placed on them. Additionally, the charm must be recast on the Fwooper every month by any wizard or witch who owned one of these birds.[3]

During the 1988–1989 school year at Hogwarts School of Witchcraft and Wizardry, Professor Filius Flitwick taught his fifth-years how to cast this charm in Charms class, in preparation for their Ordinary Wizarding Levels that year.[2]

In October 1995, Professor Flitwick had his fifth-year Charms students practise this charm, and assigned it as homework to those who could not perform it competently in class.[1]

Penelope Fawley was placed under the effects of a Silencing Charm whilst being trapped inside a portrait in her office at the British Ministry of Magic.[4]

Known uses[]

" Silencio!" cried Hermione, and the man’s voice was extinguished. He continued to mouth through the hole in his mask, but no sound came out; he was thrust aside by his fellow."
— Hermione Granger casts this spell on Antonin Dolohov in 1996[src]

Behind the scenes[]

  • Although not identified, in July 1993, when Harry lost his temper with Marjorie Dursley he may have unintentionally cast a Silencing Charm both non-verbally and wandlessly, either or both of these factors caused the already difficult spell to fail, instead causing her to swell until she resembled a balloon and float to the ceiling.[15]
