- Severus Snape: "The headmaster has sent me to tell you, Potter, that it is his wish for you to study Occlumency this term"
- Harry Potter: "Study what?"
- Severus Snape: "Occlumency, Potter. The magical defense of the mind against external penetration. An obscure branch of magic, but a highly useful one"
- — Severus Snape, an accomplished Occlumens, telling Harry Potter about Occlumency in 12 Grimmauld Place[src]
Occlumency is the act of magically closing one's mind against Legilimency. It can prevent a Legilimens from accessing one's thoughts and feelings, or influencing them. A person who practises this art is known as an Occlumens.
- "I told you to empty yourself of emotion! ... Fools who wear their hearts proudly on their sleeves, who cannot control their emotions, who wallow in sad memories and allow themselves to be provoked this easily — weak people, in other words — they stand no chance against his powers! He will penetrate your mind with absurd ease, Potter!"
- —Severus Snape to Harry Potter on the difficulty of learning Occlumency[src]
The most basic form of Occlumency, judging from Severus Snape's early lessons on the subject to Harry Potter, involves clearing one's mind — making it "blank and empty" — in order to prevent a Legilimens from perceiving one's emotions and thoughts. More advanced Occlumency involves suppressing only the thoughts, emotions, and memories that would contradict whatever it is an Occlumens wishes a Legilimens to believe; hence, it is not obvious that Occlumency is being used even if the person is lying. It requires a great deal of will power, as with resisting the Imperius Curse, as well as a high degree of mental and emotional discipline. It is also one method of resisting the influence of Veritaserum.
Occlumency is not part of the normal curriculum taught at Hogwarts School of Witchcraft and Wizardry and appears to be a rare and difficult skill.
- Severus Snape: "It appears there is a connection between the Dark Lord's mind and your own. Whether he is, as yet, aware of this connection is for the moment unclear. Pray he remains ignorant."
- Harry Potter: "You mean if he knows about it then, he'll be able to read my mind."
- Severus Snape: "Read it, control it, unhinge it... Used properly, the power of Occlumency will help shield you from access or influence. In these lessons I will attempt to penetrate your mind. You will attempt to resist. Prepare yourself! Legilimens!"

In the 1995–1996 school year, Albus Dumbledore had Severus Snape teach Harry Potter Occlumency in an effort to prevent his mind from being penetrated and influenced by Lord Voldemort. Snape was a highly skilled Occlumens, being able to successfully deceive extremely accomplished Legilimens Voldemort, but his lessons with Harry were ultimately unsuccessful. Harry was not able to repel most attacks, though it is likely that the personal enmity between him and Snape as well as the stressful events in his life that year hindered his ability. He eventually gave up attempting to learn. Harry later managed to block his connection to Voldemort, on occasion, by focusing on feelings of love and grief, rather than by using Occlumency.
- Hermione: "Dumbledore wanted you to use Occlumency! He thought the connection was dangerous... So you’re not even going to try to shut him out?"
- Harry: "Hermione, I can’t. You know I’m lousy at Occlumency. I never got the hang of it."
- Hermione: "You never really tried!"

In 1996, Bellatrix Lestrange trained her nephew, Draco Malfoy in Occlumency so that he could keep his mission to kill Albus Dumbledore a secret. Draco became skilled enough to repel Snape's attempts at Legilimency. Draco's success was due to him shutting out his compassion to become the bully he is, making it easy for him to close his mind.

The word "occlumency" comes from the English word; occlude, "to conceal". The mens, comes from the Latin for "mind".
Behind the scenes
- On the subject of Occlumency, J. K. Rowling has discussed why Draco Malfoy would be skilled at it while Harry Potter was not:
- "...I think Draco would be very gifted in Occlumency, unlike Harry. Harry’s problem with it was always that his emotions were too near the surface and that he is in some ways too damaged. But he's also very in touch with his feelings about what's happened to him. He's not repressed, he's quite honest about facing them, and he couldn't suppress them, he couldn't suppress these memories. But I thought of Draco as someone who is very capable of compartmentalising his life and his emotions, and always has done. So he's shut down his pity, enabling him to bully effectively. He's shut down compassion — how else would you become a Death Eater? So he suppresses virtually all of the good side of himself."
- Narcissa Malfoy may be an Occlumens, as she lied to Voldemort about Harry's demise without consequences. However, Voldemort may not have been using Legilimency on her at the time, as he might not have believed she would lie to him with her family's lives at stake.
- Gellert Grindelwald may also have been an Occlumens, as he lied to Voldemort about having owned the Elder Wand. However, this is unconfirmed.
- According to W.O.M.B.A.T., it may be possible that Occlumency can guard against possession.
- Voldemort employed Occlumency against Harry Potter to try and end the connection, but started to lose control during the events of 1997 and 1998.
- Harry Potter briefly used Occlumency against Voldemort, although he has never been able to master it.
- Bellatrix Lestrange was most likely taught Occlumency from Voldemort, since she stated in the Battle of the Department of Mysteries that he taught her the dark arts.
- Draco was most likely taught Occlumency by Bellatrix Lestrange, a theory made by Severus Snape when he tries, unsuccessfully, to break into Draco's thoughts.
