Memory Modifying Charm

"You will be pleased to hear that we have dealt with the unfortunate blowing-up of Miss Marjorie Dursley. Two members of the Accidental Magic Reversal Department were dispatched to Privet Drive a few hours ago. Miss Dursley has been punctured and her memory has been modified. She has no recollection of the incident at all. So that's that, and no harm done."
-- Minister for Magic Cornelius Fudge (PA3)

The Memory Modifying Charm is also called “Memory Charm”.

Modifies or erases portions of a person’s memory. A person who has their memory erased can be described as “Obliviated” (WFT).

Memory Modifying Charms are often used to uphold the International Code of Wizarding Secrecy and to avoid frightening Muggles. Officials with the Ministry of Magic who perform the Memory Charm on Muggles are known as “Obliviators.”

History and Notes

Minister for Magic Ottaline Gambol was responsible for the creation of the Hogwarts Express to transport young witches and wizards to Hogwarts. However, the secrecy surrounding the project entailed " a mass operation involving one hundred and sixty-seven Memory Charms and the largest ever mass Concealment Charm performed in Britain" (Pm)
