- "— and then, if you'll believe it, I pounced — like this — slammed him to the floor — thus with one hand, I managed to hold him down — with my other, I put my wand to his throat — I then screwed up my remaining strength and performed the immensely complex Homorphus Charm — he let out a piteous moan […] — the fur vanished — the fangs shrank — and he turned back into a man. Simple, yet effective — and another village will remember me forever as the hero who delivered them from the monthly terror of werewolf attacks."

The Homorphus Charm was supposedly a charm used to temporarily change a transformed werewolf back into their human form. It was not, however, a cure for lycanthropy, as described by Gilderoy Lockhart in his false account of his defeat of the Wagga Wagga Werewolf.
- Cecil Lee: "The Homorphus Charm. The only spell known to wizardkind that is capable of curing werewolves."
- Jacob's sibling: "It can cure werewolves? Why not just use that instead of capturing them?"
- Cecil Lee: "Well, not all of us are as gifted as Gilderoy Lockhart… He says he always casts the spell perfectly, but when I cast it, it only temporarily returns a werewolf to human form. In any case, it can be quite valuable for stopping a werewolf in its tracks."

Lockhart described the spell as being "immensely complex" and performed by placing the tip of one's wand to the throat of whoever the caster wanted to return to human form. He later admitted to having stolen the credit of saving a village from a werewolf attack from an Armenian warlock.
Contrary to Lockhart's description of the spell, however — Lockhart's books were later found out to contain a wealth of invented feats — there is no known cure for Lycanthropy. Cecil Lee of the Werewolf Capture Unit remarked that, for him, the spell only temporarily returned a werewolf to human form (believing in Lockhart's accounts, Lee assumed this was due to him having only imperfectly mastered the charm).
Homorphus is a combination of the Latin Homo meaning 'man' and the Greek morphe- meaning 'shape' or 'form'.
Behind the scenes
- It is unclear if this charm actually existed or was only another fabrication of Gilderoy Lockhart's.
- Although this spell is described as a charm, its described effects seem closer to Transfiguration. Alternatively, since the wounds left by a werewolf bite are "cursed" by werewolf Remus Lupin, and by extension the condition of Lycanthropy could be seen as a type of blood borne curse. As such, the Homorphus Charm might be a counter-curse, which can reverse the transformation.
- Although Cecil Lee was unsuccessful in trying to use it against Fenrir Grayback and his werewolf pack during their attack on Hogwarts, it would appear that rather than being a non-existent, made-up spell of Lockhart's included in his book to make him seem more impressive, (indeed, it had both a complex wand movement required to work and produced sparks), it might be because the spell is not meant to be cast from a distance, but, as peer Lockhart's own description, with the wand touching the body of the werewolf, (not unlike how some healing spells are cast by running ones wand along the wound), suggesting that the spell simply did not have long enough "reach" to affect the werewolf pack, as opposed to having no effect at all.
