Groundhogs and marmots look alike, act alike, and even belong to the same family—but they’re not exactly the same. If you’ve ever wondered whether a groundhog is just another name for a marmot, you’re not alone. Let’s break down the real differences and similarities in simple, clear language.
Are Groundhogs and Marmots the Same Animal?
Groundhogs are a type of marmot, but not all marmots are groundhogs. Groundhogs belong to the marmot family, which includes about 15 different species found across North America, Europe, and Asia. So yes, all groundhogs are marmots, but marmots come in many forms beyond the groundhog.
The confusion comes from their similar appearance and habits, but location, behavior, and size can help tell them apart.
What Is a Groundhog?
Groundhogs, also known as woodchucks, are marmots native to eastern and central North America. They’re known for digging large burrows and predicting the arrival of spring in popular folklore (Groundhog Day).
Key features of groundhogs include:
- Brownish-gray fur
- Stocky build with short legs
- Weigh between 5–13 pounds
- Live in lowland grassy areas and open fields
- Solitary by nature
Groundhogs are especially common in suburban backyards, where they can become garden pests by digging and eating crops.
What Is a Marmot?
Marmots are a group of large ground squirrels found in mountainous areas, including the Rockies, Alps, and Himalayas. They live in colonies, are more social, and tend to inhabit higher elevations than groundhogs.
General traits of marmots:
- Range of fur colors—golden, gray, brown, or even yellowish
- Larger than groundhogs—some species reach up to 15 pounds
- Social animals that live in groups
- Prefer alpine and mountainous habitats
Popular marmot species include the yellow-bellied marmot (western US), the hoary marmot (Alaska and Canada), and the alpine marmot (Europe).
Side-by-Side Comparison Table
| Feature | Groundhog | Other Marmots |
|---|---|---|
| Species Type | A specific marmot species (Marmota monax) | Group of 15+ species in the genus Marmota |
| Habitat | Lowlands, grassy fields, suburbs | Mountains, rocky areas, alpine meadows |
| Size | 5–13 pounds | Up to 15 pounds |
| Social Behavior | Mostly solitary | Live in colonies or groups |
| Common Areas | Eastern and Central North America | Western US, Canada, Europe, Asia |
Are Groundhogs More Likely to Be Pests?
Yes, groundhogs are far more likely to cause problems for homeowners than other marmots. Since they live near people in fields and backyards, they often dig near sheds, patios, and gardens. Their burrows can weaken structures and damage landscaping.

Key Differences in Behavior
Even though both groundhogs and marmots hibernate and dig burrows, there are some differences in how they live:
- Groundhogs are more likely to live alone and return to the same burrow year after year.
- Marmots often live in colonies and share tunnels or lookout duties.
This social difference also changes how they respond to danger. Marmots tend to use loud whistles or alarm calls to warn others. Groundhogs may let out a low whistle or squeal, but usually run and hide alone.
Which One Do You Have in Your Yard?
If you’re seeing a chunky rodent near your garden in the eastern or central US, it’s almost certainly a groundhog. Marmots are rarely found in suburban areas and usually stick to rocky slopes and mountain meadows.
Look for these signs of a groundhog on your property:
- Large holes near foundations or sheds
- Flattened vegetation or trampled garden rows
- Chewed stems and vegetables

Should You Remove Groundhogs or Marmots?
If they’re causing property damage, then yes—it’s best to safely remove them. While marmots in the wild usually don’t need intervention, groundhogs in residential areas often dig near homes, gardens, and driveways. Over time, they can create major problems.
You can try humane traps or natural deterrents, but in most cases, it’s easier to get expert help. Use this pest control calculator to figure out what that might cost you depending on the size of the infestation.
Conclusion
Groundhogs and marmots are close relatives, but they live very different lives. Groundhogs are a specific type of marmot that prefer grassy lowlands and often interact with humans. Other marmots, like the yellow-bellied or alpine species, stick to higher, more remote areas and live in groups.
Knowing which one you’re dealing with can help you decide what action to take. If you’ve got one near your home, don’t wait for it to cause damage—use this quick pest control cost tool to plan your next step today.
