Causes target to blend into surroundings
- "Harry looked down at his body, or rather, what had been his body, for it didn't look anything like his anymore. It was not invisible; it had simply taken on the exact colour and texture of the kitchen unit behind him. He seemed to have become a human chameleon."
- —Alastor Moody uses this spell on Harry Potter in the August of 1995[src]
The Disillusionment Charm (incantation unknown) is a spell that is used to conceal the target. The charm makes that which has been bewitched to act as a chameleon, taking the colour and texture of that which is behind and around them.
It is presumed that there are two methods of casting. It seems that if one is using the charm on themselves, they must twirl their wand around themselves as though they were wrapping themselves in rope. If, however, they are using it on an external target, they must merely rap on the target with their wand. This then produces a sensation that a raw egg has been cracked onto the person's head, as the charm travels down them, granting them near invisibility.
This enchantment is frequently used on magical creatures, according to magizoologist Newton Scamander. There is a law requiring that owners of all winged horses, including Hippogriffs, must use this charm on the creature daily to prevent muggles from seeing it.
- Moody: "Come here, boy, I need to Disillusion you."
- Harry: "You need to what?"
- Moody: "Disillusionment Charm. Lupin says you've got an Invisibility Cloak, but it won't stay on while we're flying; this'll disguise you better."

When stealing the Elder Wand from Albus Dumbledore's tomb, Lord Voldemort used this enchantment on himself so that nobody could see him; he noted that even he himself had difficulty identifying his own being.
During the Battle of Hogwarts, Draco Malfoy, Gregory Goyle and Vincent Crabbe used this enchantment on themselves so that they could watch Harry Potter, Ron Weasley and Hermione Granger enter the Room of Requirement to search for a diadem that had been owned by Rowena Ravenclaw.
Behind the scenes
- There are numerous portrayals of things being invisible, or else of people appearing noiselessly in the air; both of these may be various instances of this spell being cast.
- It isn't entirely clear how difficult a Disillusionment Charm is to cast. In Deathly Hallows, Harry remarks that Dumbledore didn't require an Invisibility Cloak because "he could perform a Disillusionment Charm so powerful that he made himself completely invisible without one," clearly impressed by Dumbledore's skill. However, later in the book, Draco Malfoy, Gregory Goyle and Vincent Crabbe use the enchantment and apparently are entirely invisible outside the Room of Requirement, even though Goyle and Crabbe are notoriously poor at magic.
