ITT:tell me about the barbarian races in your setting

This.
If I'm ever having a straight-up Barbarian race, with no justification, I just make 'em Amazons.

Only Barbarian I made loved annoying a Druid. Favorite gag was asking questions about things that were obvious to civilized people. Specifically measurement of years.
"What's a Year?"
"What's a Harvest?"
"What's a Winter?"
"What's a Season?"
"I know what ALL of those things are. Can read too."

Sadly, the PC stopped using her before I got a chance to make her friendlier with mine via a Handle Animal check. Which would have been hysterical.

On the continent I've fleshed out the most, there's three regions with cultures that can be considered barbarian.

The first is the Steppes, consisting of mounted, herding clans wandering the vast grasslands, tribes clinging to survival amongst the rocky outcrops, and tribes attempting a settled life amongst the ruins of past civilisations. In the northern part of the steppes, different cultures of nomads wander along the rivers, in the forests, and in the hills, often the victims of the mounted nomads raiding.

A vast forest in the northern part of the continent is also home to numerous tribes. While each tribe has its own traditions, there are two main sub-cultures. one sub-culture is a raiding, warrior culture, thick wooden huts built up in forest clearings, going south for spoils and riches. The other lives up in the tree tops of the tallest trees; one tribe will be scattered about in a high up area. The hunt and forage from amongst the branches.

Finally, there's the mountainous, hilly region. These tribes fluctuate in power and influence as young warlors bring tribes together under their banner, only to be killed by a rival. Each year sees a dozen petty kings trying to forge out their realm, only for most to die in the fighting. The Dwarven hold situated in the middle of the region supports these wars, hoping to keep the tribes distracted by one another rather than coming for them.

Snow elves, mountainfolk, jungle amazons and sharkpeople

What do you mean by barbarian? Warrior culture? Tribalist? Pagan/Herectic heathens?

There are none.

I convinced to the DM to make obligatory "cold place filled with barbarians" be namned Soumi (it is the finnish name for finland, Suomi, but with the o and u swapped).
After playing a finnish barbarian in an arena session (one PC had to stay behind and take care of our city whilst the others went to do a thing, a tournament was held and the winner got a go along and be played by the staying PC's player).

It's a world based on JRPG tropes. The ability to rage is genetic. You either have it or you don't, meaning that being a Barbarian is something you're born to. (Berserkers also exist, and that's a learned thing, but at higher levels they become uncontrollable monsters and no one likes having them around.)

Most Barbarians come from the Snapneck Mountains region of Sweedland, although they crop up in other places as well. The Barbarian tribes are actually fairly peacable folks. They fight with and raid each other on a regular basis as something of a social pressure release, but everyone understands that it's usually not personal. As for the peoples around them, well, none of them wants to be the one stupid enough to piss off the clans and make them band together to stomp the offender into the ground, so relationships are very cordial and trade flourishes.

And, yes, the size of the horns on their helmets (or the wings if female) are a direct indicator of their social position in the tribe.

Mine are the Vinlanders vikings who escaped to Vinland the Canada of my setting and they retained their old ways because the vikings from their continent were killed or converted to the religion of the light elves and the second race is the Ahrimdarin a race of tall gray skinned "goblins" who have a fragile alliance with the Tssarian empire but the Ahrindarin are actually dark elves and the other elven races hated them with the exception of the sea and deep elves and their ancestor god betrayed their pantheon and the 3rd barbarian race are the Satyrs a race of lesser hermaphrodite demons that only wants to rape and kill anyone in their path Slaanesh and Crossed style

Don;t say I never gave you nothin', Veeky Forums

Every race is a barbarian race in some measure, because it's a loosely stone age setting based on what's cool to me. Roughly, from Northern tundras to Southern tropical forests:
Halflings are beastmasters with white bears and mammoths as mounts.
Ogres, cyclops and giants are just very hungry and big and pretty stupid.
Orcs are your typical mongorcs, except with deinonychus mounts.
Centaurs are your typical tightly-knit, literally trample over everyone who isn't us tribes.
Humans are the ones making settlements (all the other races are nomads) and getting their shit kicked in but also trying to innovate fancy things like herding and weaving.
All the previous races are considered "Northern" and a good chunk of them (mostly orcs, humans and centaurs) are currently uneasily allied under an orc Khan's banner, with promises of conquering the South so everyone gets better grounds with abundant game and places to settle in that are not completely filled with ice, snow, rocks and murderous spirits. The PCs are a human, a half-orc, an ogre and two centaurs working for the Khan.

Gnomes... are more druids than barbarians. They're allies of natural forces like elementals and fairies and are jerks about defending their temperate plains. There's an incoming war between them and the Khan's horde, obviously.
Giant orca-people (who don't currently have a proper name) are islanders, cannibals, pretty affable but also think of themselves as the only civilized ones. Their existence is a bit of a secret, as I plan on having them trying a conquest of the continent once the PCs are settled south.
Goblins are volcano-worshippers.
Amphibians (frog-salamander-toad-etc-men) live in tropical forests' ground level and in swamps, and are specialists of alchemy.
Elves also live in tropical forests, but in the canopy, and are mostly hunters, probably cannibals too.

The northern races' cultures are way more defined than the southern ones, because that's where the PCs are.

The Pukki (also known as Goatfolk, Satyrs, Tiefs, and Goatthings) are denizens of a frozen island named Oci. They are mostly human, save for the pair of horns on their head, the strong necks that support it, and an oppressively foggy mind which inhibits their perception of reality and gets in the way of many of them holding it to any value. Because of this, most are often incredibly lazy, nihilistic, and depressed.

The Pukki make good barbarians specifically because they see life and all of its pleasures and pains as mere illusions. "The arrow through my cheek isn't real," they say to shrug it off. "Satisfying hunger is a want, not a need. I'll eat tomorrow." Their passtimes involve drugs and alcohol, the only things that break their foggy minds, as well as nearly killing themselves to rediscover value in their lives. Because of their detatched outlook on life, excessive sinful indulgence, and love for battle, they're seen as demons, fiends, and animals. Some accept this label, living like animals, wearing masks and skulls in their likeness.

Their homeland, Oci, is a land without metal. They are said to come from the Butcher, a hunter who rendered a civilization extinct entirely because they were bored and wanted sport. He was branded an animal by the gods with his horns, and he exiled himself to a place where his kin would never know a sword's blade. As a crusade rose against the Pukki, scavenged arms and armor were reforged into poorly made weapons, armor typically disregarded as the feeling of mounting wounds is seen as their sole reminder that, despite everything, life is worth living.

tl;dr: Goat people with super-power-tier autism.

They are moslty human races naive of the land that didn't accept the progress and sticked to the old world belief. They still use/venerate the magic (wich as become illegal in my western-fantasy setting), and this has lead to minor conflict with the inquisition that have now pretty much destroyed every major barbarian faction

My dark elves also have autism but to cure it is to partake in a ceremony where the child is tortured and mindraped until they become less autistic but children with Chris chan tier autism are killed off

the !notGermanicTribes who love nature, abhor advanced technology, and despise civilisation.

They're humans live in the north west of the continent, above the elven civilisation and westward of the dwarf mountains. Their land is a hilly temperate rainforest, as big as all of northern europe combined.

Their culture highly prizes fighting, hunting and communing with the spirits of nature, they mostly use guirrella tactics, hit and run, ambushes, etc against the elves who are trying to claim the land as their own.

They're known by the other races for being great hunters and outdoorsmen, mighty warriors, and for their skill at archery.

On average they reach 6 foot tall, they have light eyes, red or blonde hair, large frames, etc.

Also known for disproving of the "degneracy" of the southern cultures.

what a fucking retard

There's no cure for the Pukki's autism. This is a burden they must bear. They wouldn't be able to have a civilization if it weren't for Druids, the highfunctioning prodigal autist goat savants, who have the exact opposite problem of other Pukki where instead of everything being too foggy, everything's too clear, they see too many details and overthink everything, to the point where they get mentally exhausted from simply existing, but since they have the mental capacity to deal with managing villages, they have those duties shoveled onto them. So they indulge in vices; comfort food, self-harm, hedonism, drug use, violent and constant letting loose of their frustrations, whatever helps them cope.

Various tribes clustered in the (guess wot) cold northern part of the continent. One of these tribes is starting a campaign of alliance or conquest of other tribes to unite against a not!Roman empire further south, which has many mages and weapons other than axes, swords, and spears. the barbarians will eventually lose. If you want to have an idea, go see Shakushain's Revolt They generally keep to themselves and some even managed to build cities and cultural centers. There are very few mages among them, though.
In the eastern part of the cold north there is a number of not!Kamchadal, not!Nivkh, not!Orokh and not!Ainu hunter-gatherer tribes that don't wish to be involved in the conflict between their neighbours and the empire. They are superb hunters and can even take down a dragon, provided there are enough hunters, poison, and materials for traps.

They all, including the humans from the not!Roman empire, descend from a group of pre-humans that came from another continent further north. When a kind of ice age began to take form, they quickly sailed across to new lands. Sad to say, this ice age is already in the new continent, although its effects still aren't as severe.

Underrated.

Only humans make good barbarians.

The best barbarians are also not historical celts or germanics.
the best barbarian are wasteland Austrians.

Orcs are the barbarian race.
Imported via magic portals as a warrior army, they rebelled against their (non-human) rulers and brought down an evil empire. The orcish tribes now occupy the ruins of the empire

Is this yours?

In my setting, they're pseudo-elves of the wood/dark variety.
It's post-apoc (as in, a divine/fantasy apocalypse, think titanomachy more than revelations or ragnarok).
They used to live in the forest of the World Trees, which were the size of archtrees from DS, but tropical and fairforest-like. They built a great civilization, because they could divine the future. They knew the secrets of the Astral Silkworms that lived upon the trees, and could spin their silk into the thread of fate, and use it to divine the future.
After the end, the forest was petrified, and soil built up over the canopy to make it almost a cavern. All plant life has been replaced with fungus among the stone tree-pillars below. The once-great civilization was forced to adapt to the dark, becoming giant-insect-taming scavengers and fungus-eaters, developing darkvision, and living with basically stone-age tech. They're sneaky and Drow-y with none of the pretense, but still savage and primitive.

Barbarians are mostly orcs, hobgoblins (who are basically TNG-era Klingons in my settings,) ogres, and similar... well, 'barbaric' races. Travel between cities is EXTREMELY unsafe, so you have to be goddamned strong to survive living out there full-time. Dangerous dinosaurs are common, and in many areas of the world so are demons- a lot of magics thrown around in a war that happened centuries ago weakened the fabric of the planes, so demons often wind up popping into the Prime Material Plane by accident and going marauding.

Hobgoblin tribes have their own politics, spheres of influence, and power groups, and among most of them honor is considered extremely important. (Also in my setting, regular goblins and bugbears are kind of offshoot/mutant/throwback variations of hobgoblins, technically the same species, collectively making up about 20-25% of the given goblinoid population in the area.)

Warcraft

No!
No no no no no!
It's from the guy that did the Slaine comics. One of the characters, I think. My gift was the cringe.

kek

Lizardmen, they live in swaps and marshes and have a classical animism religion.
They might also be from space or the center of the earth but I haven't decided.

The Barbarians are a semi-loose group of races that followed the First King Mviirbiun (also called Bearbuin in the common tongue) against the Elven invaders.
The original barbarians were goliaths, huge ape-like nomadic men who wandered the forest and jungle regions to the south. They've since all but gone extinct, so not much is known about them. There were some humans who defected from the Elves, and intermingled with the goliaths, creating the race of Orcs. Orcs are the prototypical barbarian race that most people would think of. They're still hunter-gatherers, leaning more on the side of hunters. They're typically in groups of no more than around 70, lead by the smartest among them, the one that can guarantee a meal by the end of the day and an end to internal conflicts.
There are human barbarian groups, made from those who followed Bearbuin but didn't intermingle with the goliaths as much. They are more similar to the usual NotGermanic tribes, who set up more permanent settlements and will often raid nearby towns and villages, though those are often seen as more of a spiritual journey than a greedy endeavour.

But Barbarian is a CULTURAL term, not a RACIAL term you fuckin inbred. The Human, Orc and Goliath slaves that the Elves took in are from the stock that neglected their allegiance to Bearbuin. No Bearbuin = No Barbarian. Simple as that.
