There is no shortness of courage and bravery within the world of Harry Potter, both in the films and books. Although bravery is subjective, there’s an untold bravery required to exist in this world, especially as someone who lacks magic.
Although the Muggles in the wizarding world of Harry Potter tend to play minor roles throughout the franchise, they also appear to be the unsung heroes of some sort. Whether it be their aiding of wizards, their hatred for all things magic, or their boisterous personalities, some of the Muggles in the series carry an effervescent sense of bravery for however long or short they remain in the story.
Marjorie Dursley
The Dursley family in general carries less a sense of bravery rather than pure audacity so in the frame of “bravery,” this family of muggles is the least brave in the franchise, with their only bravery being to risk being so rude to wizards. Starting with Aunt Marge, clearly abuse and rudeness are traits innate to this family and she does not fall short in that category. After constant berating of Harry and the insults to his deceased parents, her Prisoner of Azkaban got her exactly what she deserved, getting blown up like a balloon.
Vernon Dursley
Vernon isn't brave, but is willing to risk magical retribution for his horrible treatment of Harry, beginning with physically keeping Harry locked in a room under the stairs, to the lengths he took to keep Harry away from Hogwarts all in Sorcerer's Stone (or Philosopher’s).

Continuing on his high horse of pride and ego, Vernon then continues to try to keep Harry locked up, knowing the amount of powerful witches, wizards, and magical creatures that stood behind Harry. As a non-magic human with nothing but flesh and blood to protect him, it was a huge risk for Vernon to keep being a horrendous person who exists in a world of magic that could harm him, time and time again.
Petunia Dursley
While the Dursley family was cruel, Petunia deserves a little more slack than her husband. Her overall dramatized emotions make her more annoyingly cowardly rather than aggressive and abrasive like the rest of the Dursley family. Being maternally related to Harry, Petunia had her own history with magic and her relationship to it; which stemmed from jealousy and evolved to hate because of her sister Lily. She does deserve some recognition; however, for choosing to raise Harry after the horrific and tragic death of his parents, despite her fear of magic (even if Dumbledore essentially cowed her into it).
Dudley Dursley
Dudley was easily unlikeable considering he was spoiled and vile toward Harry almost always. Over time, less blame is placed upon Dudley when the realization occurs that he was merely raised and conditioned under spoiled tendencies and his parents’ hate toward Harry and magic. Dudley carries his “bravery” to no surprise, by choosing to be a menace to someone who carries significantly more power than him - and the mending of their relationship later on in the series allows some grace to be held for him. Even though Harry saved his life and that was the only reason Dudley decided to stop hating him, maybe it’s because someone showed him genuine comion for once.
The Prime Minister
Although the Prime Minister believed and knew that the wizarding world was real, he didn’t necessarily want anything to do with it. He was unfortunately roped into dealing with Cornelius Fudge at the Ministry of Magic and it’s fair to say that he buried his head in the sand about the wizarding world, so much so that he tried to convince himself that Fudge was a hallucination - but his bravery emerges by being a muggle overall graced with this knowledge. The Prime Minister more so has a forced bravery thrust upon him rather than self-generated but to know details of the wizarding world and having to act on those potential threats to human lives requires a sense of bravery that not everyone could have dealt with.
Mr. Roberts
The campsite owner at the Quidditch World Cup, Mr. Roberts, also carried a sense of bravery forced upon him but it was more so obliviousness over anything else. In fact, had to be constantly Obliviated thanks to his suspicions about his new guests (the witches and wizards), and probably came out of the whole thing pretty dazed and confused when he was just trying to do his job as a groundskeeper. Still, props will be given to him in a false sense of bravery (or obliviousness) to allow the wizards their space for Quidditch as well as for the torment he and his family endured soon after by the Death Eaters in the riot.
Mrs. Cole
Mrs. Cole, the matron of the orphanage Tom Marvolo Riddle A.K.A Voldemort was raised in, receives her patch of bravery for two reasons. The first is that she aided in the childbirth of Voldemort (which in hindsight is not a simple task) but also for holding reserve toward Dumbledore when he came to take Tom to Hogwarts; not a simple test against a wizard that powerful. She knew very well that there was something very wrong with Tom and it’s a wonder what she would think of what became of him years later. Although her moment in the series appears as a brief flashback, her bravery is highly commendable over other muggles for her raising of Voldemort, her overall intellect and poise in handling herself and speaking to Dumbledore, and her care of the orphanage for such a subsequent amount of time.
Mr. & Mrs. Granger
The Grangers are not only brave for having a witch as a daughter and ing her fully, but for physically putting themselves in spaces where they could be in danger. While they are rarely seen and unfortunately are often mentioned with distaste by antagonists of the serious, the Grangers go with Hermione to Diagon Alley to purchase her school supplies with her early on in the series and are placed briefly within a world they have no place being in, still they move graciously and in brave and blind and trust in their daughter.
Frank Bryce
Briefly mentioned but wholeheartedly felt, Frank Bryce, the old gardener of the Riddle mansion, received an abrupt cameo which generated nothing but respect for him and his character. After being wrongly accused of murdering the Riddle family, he met his own fate at the hands of the true family murderer, Voldemort himself.
His bravery shines through in both of these unfortunate situations we find him in and lives on as his legacy as one of many who suffered at the hands of Voldemort, but one of few who would have been willing to stand up against him.
Jacob Kowalski
The champion of Muggle bravery goes to Jacob Kowalski. Appearing in the Fantastic Beasts continuation, not only would he and does he put his life on the line for Newt and Queenie, he comes to help and puts himself in danger for almost anyone he befriends. He wasn't fazed after almost getting killed by an Erumpent, he refused to his beloved Queenie into Grindelwald's forces, and time and time again he proves gallantry and integrity; outside of his likeability, his innate nature of courage despite lacking magic appears often and genuinely, proving bravery, heroism, and morality is not reserved to those obtaining magic.
