Who Is the Deadliest Blade in Westeros? Ranking the 10 Greatest Game of Thrones Swordsmen

If you ever need proof that sword fighting is an Olympic-level sport in the 'Game of Thrones' universe, just look at the roster of blade-swingers George R.R. Martin cooked up. From knights who actually care about chivalry to complete psychos who’d rather bash in a skull than give a fair fight, Westeros and its spin-off territory are loaded with memorable warriors. Some are out for glory, others for vengeance, and a few just want to survive long enough to see who’s sitting on whatever the current iteration of the Iron Throne is.

So, who actually earns bragging rights as the best swordsman (or swordswoman) the series and its extended universe have to offer? Fair warning: this list mixes up characters from 'Game of Thrones,' 'House of the Dragon,' and even a few lore-heavy dudes who haven’t shown up on screen but are legendary in the books. Let’s slice through the hype and see who actually deserves the title of Top Blade.

Ranking the 10 Best Swordsmen in the World of Thrones

1. Arthur Dayne – The Sword of the Morning
   Let’s get right to it: nobody swings a sword in the world of Thrones like Ser Arthur Dayne. Called 'The Sword of the Morning,' this Kingsguard knight is basically the gold standard. The guy’s so good that even legends like Barristan Selmy, himself a master, were considered only his equal—unless Arthur was wielding his famous sword, Dawn. That tipped the scales squarely in Dayne’s favor. Despite getting just a single on-screen appearance (in a flashback, no less), he’s become a mythical figure that fuels generations of wannabe knights. He took down the Kingswood Brotherhood, slayed the infamous Smiling Knight, and even unseated Prince Rhaegar at a tournament. To put it simply: he’s the measuring stick in skill and knightly behavior.
2. Barristan Selmy – The Bold One
   Even when he was clearly 'past his prime,' Barristan Selmy could still mop the floor with most fighters half his age. The ultimate knight’s knight, Barristan racked up perhaps the longest resume of heroic duels, battlefield wins, and rare respect from both sides of a war. As Lord Commander of the Kingsguard under several kings, his swordplay was basically textbook-perfect, all while following an honor code that was almost as inflexible as Valyrian steel. Even his enemies tended to spare him out of sheer respect—no small feat in this cutthroat world.
3. Daemon Blackfyre – The Rebel Blade
   Digging deeper into Westerosi history, Daemon Blackfyre—born Daemon Waters—basically turned his rumored Targaryen bastard status into a mini-dynasty by starting the Blackfyre Rebellion. He was the founder of House Blackfyre and was known as 'The King Who Bore the Sword.' This guy dominated the battlefield at the Battle of the Redgrass Field, wiped out Lord Arryn’s front lines, and allegedly fought Ser Gwayne Corbray to a draw after an hour-long duel. His reputation is stamina and technical wizardry—enough for him to nearly claim the Iron Throne.
4. Jaime Lannister – The (One-Handed) Kingslayer
   Before his infamous hand-chop, Jaime was easily among the realm’s best. Taught by none other than Barristan Selmy, the guy had style, swagger, and scary talent. While losing his dominant hand was a career setback (to put it mildly), he still managed to adapt and fight with his left—pretty impressive, considering most people would’ve just lived out their days complaining. His most famous move, of course, was the not-so-minor act of killing the Mad King and saving tens of thousands—which honestly should’ve earned him more points with the people. In his prime? He might’ve been unbeatable.
5. The Mountain – Gregor Clegane
   Nobody on this list (or any list, really) can match the sheer terror that is Ser Gregor Clegane, aka 'The Mountain.' He’s not exactly known for fancy swordplay—in fact, subtlety is not this guy’s thing. But when your opponent is basically a walking siege tower who can crush skulls with his bare hands (ask Oberyn Martell), technical finesse is kind of beside the point. His style: brute force, overwhelming size, and enough strength to make enemy armies think twice.
6. Jon Snow – The Reluctant Aegon
   With a Valyrian steel sword (Longclaw), solid training at Winterfell, and more battle experience than almost anyone else in the series, Jon actually knows how to handle himself. He killed his way through both human and White Walker hordes without the benefit (or weight) of clunky knight’s armor, and his agility kept him alive when most others would’ve been kebab’d. Yes, people claim he’s got 'plot armor,' but between duels, mass battles, and zombie fights, he absolutely earns his stripes.
7. The Hound – Sandor Clegane
   Standing at the intersection of wanton brutality and grudging morality, Sandor 'The Hound' Clegane charges into every fight like he’s got nothing to lose—because usually, he really doesn’t. He’s the kind of guy who’ll use whatever’s handy (fist, sword, broken bottle) and leverages his massive size for straight-up brawling. Not technically a knight (he hates those), but good luck outlasting him in a real fight.
8. Criston Cole – The Team Green Secret Weapon
   Over on the 'House of the Dragon' side, Ser Criston Cole is the definition of ruthless. He’s the man you put in charge when you want someone’s head separate from their body, and he’s not shy about getting dirty. Technically skilled and an absolute nightmare for his enemies, Criston was the king’s main battlefield asset during the Dance of the Dragons era—except maybe for anyone riding an actual dragon. All that plus longevity that feels almost supernatural.
9. Brienne of Tarth – The Real Deal Knight
   Brienne basically earns the gold medal for being both incredibly skilled on the battlefield and actually upholding the 'good guy knight' thing. She beat the Hound (which isn’t easy), killed plenty of soldiers and zombies, held her own against anyone who challenged her, and even took down Stannis Baratheon—though, to be fair, he wasn’t putting up much of a fight at that point. She also carried the famed Valyrian steel sword Oathkeeper, which didn’t hurt. It’s refreshing to see someone in Westeros with both talent and an actual moral compass.
10. Syrio Forel – Maestro of the Water Dance
    Here’s the wild card. Syrio Forel isn’t built like the other heavy hitters, but his style—acrobatic, nimble, darting—is totally different from your average armored tank. Coming from Braavos, his 'water dancing' swordplay focused on speed and precision instead of brute force. He taught Arya Stark everything about sword fighting worth knowing (and dropped the series' best quote: 'There is only one god and his name is Death. And there is only one thing we say to Death: “Not today.”'). The dude stood up to Meryn Trant knowing he’d probably die and made every moment count.

Some Takeaways

There’s a lot you can nitpick here (it’s Westeros; half the internet exists solely to debate this), but these are the heavyweights—swordsmen (and women) with the kill count, myth, or pure presence to back it up. The thing is, technical skill alone won’t get you far in Westeros. Surviving the politics, the monsters, and the backstabbing is also part of the package.
