Are there differences between cougars and mountain lions? Where do they live? Keep reading to find out.

Cougar vs. Mountain Lion

Mountain lion and cougar are actually two different names for the same animal. Cougars have a very large range spanning much of North and South America. Different groups of people called them by different names.

Key Differences Between Cougars and Mountain Lions

Cougars and mountain lions are the same species, Puma concolor. This big cat has the largest range of any land mammal (besides humans) in the Western Hemisphere, so it is not surprising that isolated populations developed into subspecies. These include:

The North American Cougar
Classified as Puma concolor cougar, this subspecies ranges from Canada to the southernmost reaches of the United States, through Mexico and Central America, and possibly into South America.

The Florida Panther
This subspecies was once found throughout the southern United States. Nearly hunted to extinction, around 50 individuals now live in southern Florida. Conservation efforts seek to help this population make a comeback. Florida panthers are generally smaller than their western cousins. Though distinct, it is still part of the Puma concolor cougar or North American cougar subspecies.

The South American Cougar
This subspecies is classified as Puma concolor concolor. It is known to reside in the South American countries of Argentina, Brazil, Chile, Colombia, Peru, and Venezuela.

Consider these differences in more detail.


North American mountain lions range from Canada, across the American West, east to the Florida panhandle, and into Central America. Some populations are believed to reside in South America as well.

The South American cougar lives throughout South America, including Brazil and the Andes Mountains.

Overall Size

Adults of the Florida panther and South American cougar varieties may weigh only half of what adult North American mountain lions weigh.


Cougars and mountain lions are opportunistic predators. They’ll take whatever mammals and birds they can catch, but diets vary somewhat based on the prey available in each geographic region. Mountain lions eat lots of deer and mountain sheep. South American cougars hunt wild camelids including the llama, alpaca, vicuña, and guanaco, as well as the capybara, the world’s largest rodent.


The mountain lion generally lives in cooler mountainous regions, while the cougar inhabits tropical forests. Again, the exception to this is the Florida panther of the northern subspecies, which dwells in hot, humid, swampy habitats.


All cougars have a tawny coat with a lighter underbelly. However, differences in coloration are seen depending on the climate. Mountain lions may have silvery, slightly longer fur, while cougars from warm areas – the Florida panther and the South American cougar – have a more reddish coloration.

FAQs (Frequently Asked Questions) 

Is There a Difference Between a Cougar and a Mountain Lion?

Yes. Cougars and mountain lions are the same species of big cat, Puma concolor. They are, however, of different subspecies.

Why Are Cougars Called Mountain Lions?

In a native South American language, the cat was called cuguacuarana. Settlers shortened the word to “cuguar,” and later altered the spelling to “cougar.”

When settlers from Spain came to North America, they called the cougar gato monte, meaning “cat of the mountain,” as well as leon, the Spanish word for lion. These terms described both the cougar’s appearance – similar to a female African lion, but smaller – as well as its mountain habitat. In English, these terms were combined to form “mountain lion.”

What Other Names Are Used for Cougars and Mountain Lions?

The Incas called mountain lions “pumas.” “Panther” was a term used by Europeans to describe big cats with a solid coat. This name was thus given to the sandy-colored cougar as well as a related species, the solid black morph of the jaguar. In some places, they are also called painters or catamounts.
