The witches and wizards in the Harry Potter universe are gifted with extraordinary abilities in magic. Even the witches and wizards that are nearly squibs would undoubtedly be envied by the powerless muggle world, and once the magicians in the Harry Potter world have the appropriate tools and training they can often make near miracles happen with nothing more than a flick of their wand.
A wizard's wand is like a funnel for their magical power, it allows them to concentrate their energies in order to more powerfully and effectively cast spells. However, there are some witches and wizards in the wizarding world that are even more extraordinary than the average magician (if you could call having superpowers average). Some particularly exceptional spell casters are capable of using magic without even having a wand. They are certainly few and far between, but here are the 10 most talented Harry Potter witches and wizards who don't need a wand to make magic happen.
Sirius Black
Sirius Black is a character who seems to be quite talented and skilled in all types of magic, but it's easy to forget that he excels at one of the most important and unique forms of magic in the entire wizarding world. Sirius is a quite talented animagus, his ability to transform into a giant black dog has actually saved his life on many an occasion, and the ability to transform into the animagi form and back is one of the most difficult and delicate skills in magic. When you consider what kind of spells require a wand it makes the skills of an animagus all the more impressive, and it's wild that Sirius could do it when he was still a child.
Lily Evans
Lily Evans seems to have been a very clever and talented witch throughout her career at Hogwarts School of Witchcraft and Wizardry, but it's important to remember that this muggle born witch actually discovered her magical powers all on her own.
Her skills were very minor before she went to Hogwarts, and her friend Severus Snape undoubtedly helped her along in mastering some forms of wandless magic, but Lily was born in the normal human world. She had no reason to even imagine that she had magical powers, so the fact that she managed to actually make things happen is pretty exceptional.
Severus Snape
Severus Snape was obviously good at wandless magic in the sense that he was one of the most skilled potion masters in the entire wizarding world, but what made Snape truly an exceptional wandless wizard was his abilities as an occlumens. Occlumency is the art of shielding one's own mind from the attacks of a legilimens (a legilimens is a wizard who can search other people's minds magically). Severus and his allegiance to the dark side or the light side of magic was one of the biggest mysteries in all of Harry Potter, and Snape's abilities to block the dark lord out of his thoughts showed what an extraordinary wandless magician he was.
Filius Flitwick
It's somewhat ironic that Professor Filius Flitwick was the charms instructor at Hogwarts School of Witchcraft and Wizardry, because he was likely one of the most skilled wandless wizards in the entirety of Hogwarts castle. Professor Flitwick probably had a bit of an edge over any average wizard when it came to wandless magic though. Filius is undoubtedly a mostly human wizard, but he appears to have a bit of goblin blood in him as well. As anyone who is familiar with the Harry Potter universe knows, goblins are veritable experts at wandless magic, and they can do nearly as much as wizards do without a wand.
Harry Potter
Lily Evans did some pretty impressive things when she was still in the dark about the existence of magic or about the fact that she was a witch, but what she did really doesn't hold a candle to the kind of things that Harry Potter has managed to do without his wand.
Harry's abilities with wandless magic have come in handy quite a few times over the course of his life, but his most memorable wandless tricks occurred shortly before he got his letter to Hogwarts. Minor expressions of magic are to be expected from magical children, but talking to a snake and making a glass window disappear is a pretty big deal.
Albus Dumbledore
It comes as no surprise that Albus Dumbledore is one of the most talented wandless magicians in the entire Harry Potter universe, because his abilities and natural talents for magic are pretty much unparalleled in the wizarding world. Most wizards require a certain amount of effort to use their magic without their wand, but Dumbledore seems quite comfortable using wandless magic with literally the wave of his hand. He seems to love showing off minor trickery to the students with his wandless magic, but when things get serious he can pull out the big guns, for instance when he was dueling Voldemort he managed to force Harry out of the fray without using his wand to keep him at bay.
Tom Riddle
Tom Riddle grew up to be the darkest and most dangerous wizard in the history of wizardkind, but Albus Dumbledore should have had an idea of how great his power may have been right from the moment that he met Tom. Most young children, even those who are raised in the world of magic, seem to do magic accidentally without any intention or control behind it. But Tom Riddle, a boy who had been raised in the muggle world, not only understood that he had magical powers before he discovered the magical world, but he could even use it how he wanted to.
Gellert Grindelwald
There are few people in the world that have ever demonstrated themselves to be Albus Dumbledore's possible equal or even superior, but Gellert Grindelwald is one of those few. Grindelwald's greatest power seemed to be his ability to convince so many witches and wizards to take his side, but he has demonstrated some seriously intimidating wandless magical powers as well.
Like Dumbledore, Gellert seemed to be quite talented and adept at making magic happen with nothing more than a wave of his hand, and his abilities to make objects, people, and even himself levitate is something unlike anyone in the wizarding world has really ever seen.
Nymphadora Tonks
Every witch and wizard in the world is born with some inherent magic within them, but there are a select few who have such a strong power or ability that they barely even have to try in order to make magic happen. And Nymphadora Tonks is one such witch. Tonks is a talented witch in nearly every arena of magic, but she has also been blessed with the extraordinary ability of being a metamorphmagus. A metamorphmagus is a shapeshifter that can change their appearance at will, and unlike other magicians like animagi, a metamorphmagus can transform their appearance in nearly every way imaginable.
Queenie Goldstein
So there are extraordinary witches and wizards like Tonks who can do some kinds of magic almost effortlessly, and then there are witches and wizards like Queenie Goldstein. Queenie Goldstein's powers of legilimency are so strong that they're not even effortless, they're literally a natural part of her human existence. Queenie's mind reading powers are so intense that she can't even really turn them off, and there may be other people in the wizarding world like her, but as far as the Harry Potter and Fantastic Beasts canon goes, Queenie is quite literally the most powerful and accomplished legilimens that we've ever seen.
