Types of Mountain Lion in Illinois
No, there are no wild mountain lion types living in Illinois today. Historically, the North American mountain lion was the only subspecies found in the state, but it was extirpated by the mid-1800s due to habitat loss and hunting. While mountain lions are still found in the western United States, they are officially considered extinct in the wild in Illinois. Any large feline types seen in the state today are almost exclusively the native bobcat, which has a thriving and expanding population.

What kind of mountain lion used to live in Illinois?
The North American mountain lion, also known as the cougar or puma, was the only type native to Illinois. They were once the state's top predator, roaming from the northern prairies to the southern forests. Unfortunately, they could not survive the rapid settlement of the state and were gone long before modern wildlife management practices were established.
Are there different species of cougars in North America?
While they are all one species, Puma concolor, there were once many regional subspecies recognized across North America. Today, scientists generally group them all into one single North American subspecies. Regardless of the name, cougar, mountain lion, or panther, none of these types currently have a resident population in the Illinois wilderness.
Can any mountain lion species return to Illinois?
It is highly unlikely that mountain lions will re-establish a population in Illinois in the near future. While young males from western states occasionally wander into the Midwest looking for new territory, the lack of large, connected wilderness areas in Illinois makes it difficult for them to find mates and settle. The state's landscape is now better suited for smaller predators like the bobcat.
How do mountain lion types differ from Illinois bobcats?
Mountain lions are a 'large cat' type, while bobcats are considered 'medium-sized.' A mountain lion is about four times the weight of a bobcat and has a completely different body shape, including a very long tail. Bobcats are the only wild cat type currently breeding in Illinois, and they are well-adapted to the state's mix of forests and agricultural land.
What is the closest wild mountain lion population to IL?
The nearest stable populations of mountain lions are in the Black Hills of South Dakota and the mountainous regions of Nebraska and Colorado. These western populations are the source of the rare 'vagrant' individuals that occasionally appear in the Midwest. While these cats can travel hundreds of miles, they are still far from establishing a new home in Illinois.
How many mountain lions are in Illinois today?
There are zero wild resident mountain lions in Illinois. Confirmed sightings of individual cats are extremely rare, occurring perhaps once every few years. These are always solitary animals passing through and do not represent a permanent population. Any mountain lions in the state are more likely to be found in accredited zoos or authorized wildlife sanctuaries.
