We used Saturday Night Science to analyze Montana’s most recent Census data to determine the divorce rate for each city in Montana based on the percentage of currently divorced residents.
The city with the highest divorce rate in Montana is Lewistown, with 16.0% of people over 15 years of age being divorced, per the most recent census data. The city with the lowest divorce rate in Montana is West Yellowstone.
Montana is 5.0% divorced overall. There are some 44,675 people living in Montana over fifteen years of age who are divorced. You can compare that to the 28,339,199 Americans who are currently divorced.
Isn’t the divorce rate in America close to 50%? Yes indeed. But we’re measuring something else; we are looking at counts and percentages of people over 15 years old who are currently divorced. That 50% statistic is for the percentage of people who have ever been divorced.
So now that we have you biting your nails, rethinking your worldview, and pulling out your hair, let’s look at the places in Montana with the highest rates of divorcees.

How We Determined The Places In Montana That Get Un-Hitched The Most
We used Saturday Night Science to look at the U.S. Census Bureau on divorce rates. Because who likes tracking misery more than the U.S. government?
Specifically, we looked at the 2020-2024 American Community Survey table S1201 — Marital Status. Pretty straightforward on that front — we just had to extract the following column of data:
Today, the analysis focuses on the 53 places in Montana with a population of over 1,000.
- Population 15 Years and Over -> Divorced
We ranked each place by the percentage of divorcees over 15 years of age from highest to lowest. We crowned the divorce capital of Montana the place with the highest incidence of divorcees, Lewistown.
And if you’re trying to avoid divorce, check out West Yellowstone, the city with the lowest divorce rate in Montana. We updated this article for 2026 and this list is our eleventh time ranking the cities in Montana with the highest divorce rates.

Summary
Getting Some Closure In Montana After Untying The Knot
We now have a sense of what places in the Treasure State don’t pay much attention to the whole “’til death do we part” phrase.
The cities with the highest divorce rate in Montana are Lewistown, Deer Lodge, Cut Bank, Malta, Glasgow, Ronan, Columbia Falls, Thompson Falls, Colstrip, and Anaconda-Deer Lodge County.
Try to keep in mind that the reason cities rank where they do in Montana could be because of the age, education, and income distribution, as all of those things impact the rate of divorce.
