Our world is home to some pretty incredible species. The diverse animals that make up the natural world are equipped with a broad range of adaptations that enable the species to thrive. One of those adaptations? Speed.

There are a lot of quick animals roaming the Earth. There are fish that can swim unbelievably fast, as well as birds that can swoop in at a startling pace. Avians are actually the fastest animals in the world, sometimes reaching speeds of well over 250 miles per hour. It’s pretty incredible!

When it comes to the fastest mammals on Earth, one clear winner comes to mind: the cheetah. However, you’ll be surprised to know the cheetah actually isn’t the fastest mammal in the world! Discover the top 20 fastest mammals on Earth. You’ll definitely find some surprises!

20. Zebra

It’s standard for zebras to travel substantial distances in a day due to their grazing patterns.


The zebra is the 20th-fastest mammal on Earth. Its speeds reach somewhere between 35-43 miles per hour.

19. Onager

Persian Onager

Onagers adapt to weather changes by growing a curly, dense coat for the winter.


The onager is a donkey-like mammal with the ability to reach incredible speeds. These creatures can reach between 37-43 miles per hour when running.

18. Greyhound

The greyhound is the 18th-fastest mammal on Earth and the fastest domestic dog in existence. These dogs have been bred for racing over the course of history, so their speed is incredibly intentional. Greyhounds run at a speed of between 37-44 miles per hour.

While greyhounds have been bred, historically, for the purpose of racing, the Humane Society generally regards greyhound racing as inhumane. The practice is now illegal in almost all of the states in the US.

17. Kangaroo

Interestingly enough, the kangaroo is one of the fastest mammals in the world. These marsupials don’t run like most mammals on this list. Instead, they hop at an astounding pace and distance. This results in kangaroos moving 31-44 miles per hour during a short sprint.

16. African Wild Dog

The African wild dog is a wild canine with the potential for incredible speeds. They’re hunters, and when they kick their pace up to a full sprint, they can reach 44 miles per hour. Generally, their longer speeds are between 35-37 miles per hour.

15. Jackrabbit

Jackrabbits can leap up to 20 feet in one mighty hop.


Small but mighty, the jackrabbit is one of the fastest mammals in the world. They are equipped with strong hind legs that enable them to reach an overall pace of 36-45 miles per hour. Like the kangaroo, jackrabbits don’t run, they leap! They can leap between 10-20 feet in a single hop.

14. Hare

Similar to the jackrabbit, the hare is one of the fastest mammals on Earth. Hares can reach slightly higher speeds than the jackrabbit, with a range of between 35-50 miles per hour. They can’t sustain their top speeds for all that long, but in short bursts, they can move at an astonishing pace!

13. Lion

Lion run

Speed is one of the lion’s greatest assets during the hunt.


The first big cat on the top twenty list of fastest mammals on Earth is the lion. Lions are hunters, too, and their speed is one of their greatest assets. Lionesses in particular have been known to reach up to 50 miles per hour during a hunt.

12. Impala

jumping animals - impala

The subspecies of impalas differ somewhat in size. Impalas are also sexually dimorphic, so females and males have significantly different characteristics.


The impala is the first antelope on this list, though there are many more to come. These amazing animals can run between 37-50 miles per hour. They’re slender, making them amazing aerodynamic athletes.

11. Grant’s Gazelle

The Thomson’s gazelle is yet another antelope with absolutely amazing speeds. Thomson’s gazelles are unique due to their long-distance endurance. While they can reach 50 miles per hour in a sprint, their endurance enables them to outrun faster mammals. For example, they can run quickly for longer distances than cheetahs, making it possible to escape the second-fastest mammal on this list!

6. Domestic Horse

Thoroughbreds have been specifically bred for racing starting in the 17th century.


Quickly diverging from the antelope category, an equine takes the sixth spot for the fastest mammal on Earth. The domestic horse has been known to reach almost 55 miles per hour at a full-blown sprint. Thoroughbred horses are the fastest of domestic horses, bred specifically for speed.

The pronghorn, also known as the American antelope, is the third-fastest mammal on Earth. It’s also the fastest long-distance animal in the world. These antelopes run at a pace of between 50-60 miles per hour, but they can sustain their top speeds for half a mile or so at a time.

2. Cheetah

Cheetahs have been recorded as reaching paces of over 71 miles per hour, but these measurements have been discredited. They run at a pace of between 60 and 65 mph, which is still incredibly fast!

Unsurprisingly, the cheetah ranks as one of the fastest mammals on Earth. While it’s generally thought to be the fastest mammal, it actually takes second place. These big cats can run at a pace of between 60 and 65 miles per hour. However, they’re only capable of short bursts. They often don’t sprint for longer than a minute at a time.

1. Mexican Free-Tailed Bat

Mexican free-tailed bats can also fly at higher elevations than most bats. They’ve been spotted at altitudes of 10,800 feet.

The Mexican free-tailed bat takes the first-place spot for the fastest mammal on Earth. These incredible bats can reach 99 miles per hour while flying, making them one of the fastest-flying animals in the world. They are medium-sized bats, generally only 3.5 inches long. While they may be small, they are clearly mighty!


These animals are pretty amazing! From the zebra, to the kangaroo, to the tiny Mexican free-tailed bat, these mammals exhibit some astounding speeds. Big and little, heavy and light, these mammals demonstrate the incredible diversity of the natural world.
