The horned helmet is one of the most instantly recognizable traits of fantasy barbarians: whether a simple metal skull-cap fitted with cows' horns, elaborate metal headgear with towering, wrought protrusions or just the skull of a horned creature worn as a hat, this serves as a clear and recognizable identifier that the people sporting such helms probably aren't streaming out of the depths of the forests for some quiet tea and biscuits.
The horned helmet stereotype was started by the Romans, who attributed such helmets indiscriminately to the barbarian peoples to their north. This was later reinforced by some archeologists digging up a Viking helmet near a couple of drinking horns and assuming that they had once been one piece. This led to horned helmets becoming an archetypal accoutrement of Celtic, Germanic or generally pseudo-European barbarians in later times.
Visually, besides calling back to the forest-dwelling tribal groups of ancient history, horned helmets also serve to provide a fearsome, bestial look to their wearer, enlarging their silhouette and making them seem particularly monstrous and inhuman, displaying their status as a barbarous figure. Consequently, heroic barbarians tend to wear helmets with smaller and less intimidating horns, while villainous figures will be found sporting ones with larger and more menacing projections. In-universe, these helmets may be worn as a deliberate invocation of the above themes, so as to intimidate and cow their wearer's foes. Alternatively, the horns may be trophies of successful hunts or simply cultural affectations.
In cases where the barbarians in question are of a particularly monstrous bent, such as them belonging to an entirely non-human species, they may sport organic horns as part of their natural appearance without the need of helmets. Sometimes this will happen as part of a gag where they will seem to wear helmets at first and take them off to reveal that their horns are actually part of their body. See also A Load of Bull, as minotaurs are often portrayed as very barbaric or bestial beings.
In reality, horns on a helmet would actually sabotage its effectiveness, providing a joint to catch incoming blows rather than deflect them. As such, while horned helmets were sometimes created in real life, these were strictly ceremonial and decorative pieces and not usually meant for being used in battle. Horned helmets may be replaced by the (equally unhistorical) winged helmets.
For the other parts of the stereotypical barbarian ensemble, see Barbarian Longhair, Beard of Barbarism, Braids of Barbarism and Pelts of the Barbarian. See also Horny Vikings, for a group most often seen sporting this type of accessory. May overlap with Horns of Villainy, if the barbarians are portrayed as antagonistic.
- Capital One zig-zags this with its use of Vikings as a metaphor for other cards over-charging (pillaging) customers. Some Vikings wore metal helmets with horns, some metal helmets without horns, and others with nothing at all on their heads.
- Fist of the North Star: Uighur the Warden has a helmet with two large horns. Being the warden and enforcer of Cassandra, he rules the prison city through savagery and iron fists.

- A Private Story On Third Street: Parodied. One of the time-displaced footsoldiers is a (female) Viking who tries countless times to explain to the neighbourhood kids that yes, she's really a Viking, and no, Vikings didn't have horns on their helmets. Eventually she gives up and just tapes some paper horns on every time she goes to visit, causing the kids to recognise her as a Viking instantly. After a while of this she starts to wonder if maybe she's the crazy one, and Vikings did always have horns. The author's notes explain this as a Historical In-Joke about how Viking-founded settlements tended to go native very quickly and leave behind little evidence of their old culture.
- Asterix: Horned helmets are very common among the various barbarian peoples, even though their real-life counterparts wore no such things, in contrast to the Romans' standardized and less flamboyant armor.

- Shadowrun: Trolls are the largest human metavariant, the likeliest of the main five races to be perceived as big, stupid and violent bruisers and often found working as mercenaries, hired muscle and bouncers. Fittingly, their physical traits include large, prominent horns, often more than two, growing from their heads.
- Orcs, especially warlords and other leaders, tend to sport large helms adorned with the horns of large animals.
- The Beastmen, a race of vicious and animalistic savages, tend to sport large, goat- or cow-like horns by nature. They have an entire caste system based around this, in fact, in which rank is determined by the size and number of one's horns. Beastmen with no horns at all, called brays, are barely tolerated as slaves, outcasts and cannon fodder. Ungors, who have horns on human heads, form the lowest rank of actual Beastman culture; the larger their horns, the better their lot. Gors sport fully caprine heads with large, curling horns. Ones with particularly fine horns and/or additional pairs, who also tend to be the largest and fiercest Beastmen around, are called Bestigors and form the elite of Beastman society; Beastman warlords are inevitably Bestigors. Consequently, it's fairly easy to tell who the fiercest, most ferocious and most important member of a warherd is by simply looking for the one with the largest, showiest horns.
- The Warriors of Chaos often wear face-concealing helmets adorned with gigantic metal horns, sometimes with skulls clasped between their tips. Often, Chaos mutations can lead to them growing organic horns without the need for helmets.

- The Elder Scrolls: Given that the region of Skyrim and its people, the Nords, are heavily influenced by Viking culture, it's no surprise that many of the heavy armor sets forged in the region have helms with some form of horns or wings on them, but the Iron Helmet particularly bears the greatest resemblance to traditional depictions of barbarian/Viking armor, though the horns are curved downward instead of skyward. This also seems to be only restricted to the region of Skyrim itself — while other armor sets forged elsewhere in Tamriel each have their own regional differences, horned helmets aren't among them. The promotional material for Skyrim and the Greymoor DLC for The Elder Scrolls Online both feature Nords wearing a horned Iron Helmet and are both set in, well, Skyrim.
