Key Points:

  • Its striped fur camouflage helps the Siberian tiger blend into its surroundings while seeking prey.
  • Grizzly bears are opportunistic predators. They may fish in a lake or river, take down a deer they can capture, or scavenge.
  • While there are brown bears in Asia, grizzly bears are a specific subspecies only found in North America. Siberian tigers do hunt brown bears in their native habitat.

Siberian tigers, also called Amur tigers, are a tiger subspecies that is found in Russia, China, and possibly in some parts of North Korea. This is opposed to the Indian Subcontinent and Southeast Asia, where they are mostly known to live. Meanwhile, the grizzly bear is one of the largest, deadliest bears in the world. As with many large mammals, it’s hard not to wonder which of the two would come out on top in a fight. Today, we’re going to imagine a Siberian tiger vs grizzly bear battle and use the available data to figure out which creature would kill the other.

We’ll show you which animal has the greatest advantages and how the fight would turn out.

The greatest differences between a Siberian tiger and a grizzly bear are based on their morphology and hunting methods. Siberian tigers are quadrupedal felines with long bodies and long tails which prefer to stalk and ambush their prey. Grizzly bears are semi-quadrupedal creatures with thick skin that sometimes stand on their hind legs and engage in opportunistic predation along with scavenging.

These unique qualities will play a big part in determining which of the animals wins the battle of grizzly bear vs tiger. Yet, they’re not the only ones that we must explore. We’ll have to examine these animals to see which is best suited to survive this fight.

What Are the Key Factors in a Fight Between a Siberian Tiger and a Grizzly Bear?


Grizzly bears have thick skin and fur that protects their vital areas.


Determining whether a Siberian tiger or a grizzly bear wins a battle against each other is a matter of considering many factors. We’ve come up with five different elements that will ultimately determine the winner of grizzly bear vs tiger. We’ll present data on each animal and show you which of them has the advantage.

By the time we’ve finished quantifying their advantages, we’ll know if the bear or tiger is going to survive this battle.

Siberian Tiger vs Grizzly Bear: Size

The Siberian tiger and grizzly bear are very similar in size. That sentence may seem like a mistake, but the Siberian tiger is the largest tiger species in the world. They can weigh up to 770 lbs, measure 11 ft long, and stand 3.5 ft tall. That’s at their very largest, though.

Grizzly bears measure about 10 ft long, 4 ft at the shoulder, and can weigh up to 700 lbs or much more on average. The largest grizzly bear on record is massive compared to a Siberian tiger.

The grizzly bear has a size advantage on average.

Siberian Tiger vs Grizzly Bear: Speed and Movement

Siberian tigers are faster than grizzly bears on land. The average grizzly bear can reach speeds of 35 mph on land, which is very fast. They can even swim much faster than they seem capable of doing, about 6 mph.

Siberian tigers are capable of reaching top speeds between 40 and 50 mph, but they cannot hold this speed for long. They can also leap for over 20 feet when they are launching an attack on their prey. They swim well, but we don’t have an accurate top swim speed for them.

Siberian tigers have the land speed advantage.

Siberian Tiger vs Grizzly Bear: Defenses

Both the grizzly bear vs tiger have good defenses. A grizzly bear has thick skin, a thick layer of fat and muscle, a massive body, and the ability to stand on its hind legs to scare off would-be attackers.

Meanwhile, Siberian tigers have their size and their camouflage to help them blend into their environment. Even if they found themselves in danger, they could run away. Their skin is not as thick as a grizzly bear, so they’re a little more susceptible to attacks. Still, Siberian tigers are apex predators that prefer to kill in a single strike. Resistance is not something they often face.

Grizzly bears have better physical defenses.

Siberian Tiger vs Grizzly Bear: Offensive Capabilities

Grizzly bears are utter powerhouses in terms of offensive capabilities. They have a very powerful bite with 975 PSI bite power, a strong swipe, and long, sharp claws that can tear enemies apart. They can follow their prey into the water or wait for them at the bottom of trees. These animals are very powerful and dangerous.

Siberian tigers are built for killing. They are great stalkers and hunters, and they use their 1,000 PSI bite power, massive 3-inch canines, and 4-inch claws to dig into prey. They have a powerful, unforgiving bite that lets them clamp down on their prey’s neck and suffocate them.  

Even if they don’t bring down their prey right away with an ambush, they can still wear them down and overwhelm them.

Siberian tigers have an offensive advantage.

Siberian Tiger vs Grizzly Bear: Predatory Behavior

Grizzly bears are opportunists that take whatever meals they stumble upon. That may be fish in a river or an unlucky deer. They’re also scavengers that take meals from other animals that are too small to fight them off.

Siberian tigers are ambush predators. They expertly stalk and kill prey, bursting forth from tall grass or a hidden alcove to bite on the prey’s neck to break it or choke them to death. They can also kill through exsanguination with massive bites to the animal’s vital areas.

The Siberian tiger certainly has the predatory instinct to start the fight devastatingly.  

Who Would Win in a Fight Between a Siberian Tiger and a Grizzly Bear?

The Siberian tiger is a large cat, and it would probably take down a grizzly bear.


In the battle of the grizzly bear vs tiger, a Siberian tiger would win a fight against a grizzly bear. The Siberian tiger is an ambush predator, and it’s the only big cat that comes close to the grizzly bear in terms of size and power. Size isn’t everything, though.

Siberian tigers are born killers that hunt with precision and devastating power. This combination leads us to believe that a Siberian tiger would get the drop on the grizzly bear, and it would deliver a deadly attack that the bear cannot counter.

In Asia, confrontations between brown bears and Siberian tigers are more common than you’d think. In fact, Siberian tigers actively hunt brown bears. Even brown bears sometimes seek out Siberian tigers to steal their kills. However, grizzly bears, a subspecies of brown bears, are only found in North America.

A massive bite to the bear’s neck would be devastating, and the bear would have a very, very hard time bouncing back. However, if the bear’s fur, fat, and muscle managed to turn that fatal strike into merely a powerful one, then the fight could drag on. That’s if the tiger didn’t manage to maintain a grip on the bear’s throat.

In that case, the bear could land a couple of powerful swipes or a bite that would hurt the tiger. Yet, the feline is more lithe and agile, and it would probably be more capable of dodging attacks than the grizzly. Even if the bear stood on its back legs to force the tiger to come close, it would need to time an attack to effectively kill the tiger.

The battle would be bloody and brutal any way you look at it, but we think the Siberian tiger wins this fight.

Another Animal That Could Take Down a Tiger: Tiger vs Wolf

A tiger would win over a wolf with ease. At a weight of 600 pounds, the tiger is roughly three times heavier than a wolf. The tiger has a top speed of 40 mph, which is more than enough to keep up with or outpace wolves. Because they often hunt in packs, wolves rarely come into contact with animals as dangerous as tigers. When they are so heavily outnumbered, they have little combat experience.

Tigers have two options for ending the conflict. They might ambush and kill a wolf, but it’s unlikely because wolves have sharper senses and would almost certainly be aware that a tiger is at least nearby. Yet, the prey only needs to be stunned for a brief period of time for the tiger to strike them with its entire body weight of 600 lbs.

While a tiger may win, it’s important to remember that wolves hunt in packs and may be able to take down a tiger if a tiger was faced with a pack of wolves.
