You’ll spot most polar bears roaming on and near the Arctic sea ice in five countries: Canada, Alaska (U.S.), Russia, Greenland, and Norway. Polar bears really depend on sea ice for hunting seals, so the ice-packed stretches of the Arctic are where you’ll find the biggest populations.
Just imagine those endless white plains, where bears wait by seal breathing holes or trek for miles across shifting ice. It’s wild, honestly. The next sections highlight where polar bears gather, how sea ice shapes their territory, and what lets them survive in such a harsh place.
Where Do Most Polar Bears Live?
Most polar bears stick to places where Arctic sea ice forms and lasts long enough so they can hunt seals. You’ll see the largest groups in five countries around the Arctic Circle, and Canada actually has the most.
Polar Bear Distribution Across Arctic Countries
Polar bears show up across five main range states: Canada, the United States (Alaska), Russia, Greenland, and Norway (Svalbard). The presence of sea ice really determines where these bears can live. They need it for hunting, traveling, and sometimes even for denning.
Researchers group bears into about 19–20 populations to keep track of their numbers and health. Some populations cross over into different countries’ waters, so there’s a lot of shared management.
Population sizes shift by region. Places with steady sea ice and plenty of seals support more bears. Where ice shrinks, you’ll see bears fasting longer and wandering farther in search of food.
Significant Polar Bear Populations in Canada
Canada’s got more polar bears than anywhere else. You’ll find big populations around Hudson Bay, the Beaufort Sea, and the Canadian Arctic Archipelago.
Hudson Bay, especially near Churchill (which gets called the “polar bear capital of the world”), is famous for its bears. Researchers have studied these groups a lot and noticed clear seasonal changes as the ice melts and freezes.
With summer ice melting earlier and coming back later, bears in Canada spend more time on land and go longer without eating. Local wildlife agencies keep a close eye on these populations and run programs for safety and research.
Arctic Regions of Alaska and the Chukchi Sea
In Alaska, polar bears mostly stick to the northern coast and the sea ice over the Chukchi and Beaufort Seas. You might spot them along the northern Alaska coastline, where the Chukchi Sea bears mix with Russian bears across the Bering Strait.
These bears rely on pack ice and moving floes to hunt seals. The Chukchi Sea bear group shows both resilience and vulnerability to changing ice. Shifting sea ice sometimes pushes bears closer to shore, which leads to more run-ins with people and can stress out communities that rely on subsistence hunting.
U.S. and Russian scientists share info about this cross-border group.
Notable Habitats: Greenland and Svalbard
Greenland has several polar bear populations along its long eastern and western coasts. Bears use coastal ice and fjords to hunt and to travel between denning and feeding spots. Some Greenland bears cross into Canadian waters, so international tracking matters.
Svalbard (Norway) is home to a well-known Arctic population that’s closely tied to local sea ice. You can spot polar bears in Svalbard where ice sticks around the archipelago. Both Greenland and Svalbard populations feel the pressure when summer sea ice disappears, making hunting tougher and forcing bears to roam farther.

Polar Bear Habitat and Adaptations
Polar bears stick to frozen seas and coastal edges where they can find seals and rest on ice floes. You’ll see how they use sea ice to hunt, what they eat, and how they travel across the Arctic to find food or mates.
Dependence on Sea Ice Habitat
Sea ice is the main platform polar bears use for hunting, traveling, and breeding. They rely on both multi-year and seasonal Arctic sea ice to reach seal breathing holes and pupping spots.
When ice forms near shore, it creates hunting zones where ringed and bearded seals come up for air. Polar bears often wait at these openings or near seal dens.
If sea ice disappears, bears end up on land or swimming longer distances. That really ramps up their energy use and risks, especially for cubs. Pregnant females still dig snow dens on shore or on thick ice to keep their newborns safe and warm.
Typical Prey and Hunting Grounds
Polar bears mostly go after seals for food. Ringed seals are the top choice, but they’ll take bearded seals when they can.
Bears hunt at seal breathing holes, at dens in snowbanks, and along leads—those narrow gaps of open water between ice floes.
Sometimes you’ll see them scavenge whale carcasses or go after walrus calves or bird eggs if seals are hard to find. Their big size, thick fat, and hollow fur help them survive the cold and swim those long distances between hunting spots.
Range, Migration, and Seasonal Movements
Polar bears roam all over the Arctic—think Alaska, northern Canada, Greenland, Russia, and Svalbard. Most of them stick to areas north of the Arctic Circle, but some groups wander south into Hudson Bay when the ice melts.
These bears basically follow the ice as it freezes and thaws. In spring and early summer, they spread out across new ice to hunt seal pups.
By late summer, you’ll see them heading to shore or hanging out on leftover ice floes, just waiting for winter to bring the freeze again. Sometimes, when the sea ice pulls way back from the shore, polar bears have to swim long distances or shift their range just to find good hunting spots along ice edges and leads.
