"Shouldn'ta lost me temper, but it didn't work, anyway. Meant ter turn him into a pig, but I suppose he was so much like a pig anyway there wasn't much left ter do."
Rubeus Hagrid on his attempt to turn Dudley Dursley into a pig[src]

Human to pig was a Transforming spell used to transform a human target into a pig.


Circe was fond of using this spell to turn sailors into pigs in ancient Greece.

On 31 July 1991, Rubeus Hagrid, despite being forbidden to perform magic, attempted to transfigure Dudley Dursley into a pig, but only gave him a tail.

Behind the scenes

  • In an early script for the film adaptation of Harry Potter and the Order of the Phoenix, Harry threatened to use this spell on Dudley once again when Dudley and his gang tormented Harry near the film's start.[1]
  • Hagrid mentions that he tried to turn Dudley into a pig, but supposes that must not have worked because he was already too much like a pig. Provided Hagrid was not simply joking to amuse Harry after successfully, purposefully giving Dudley a pig's tail, this is might be an instance of Hagrid's magic not working fully, due to his snapped wand. It is also possible that Hagrid wasn't skilled enough, as human transfiguration is very difficult.
  • It is unknown if this spell is specifically to turn humans into pigs, or if it could turn any creature into a pig. It may be even be the same spell Professor McGonagall used to turn her desk into a pig. If it is, this means that it can also be used on inanimate objects.
