In many parts of Colorado, you'll find a plethora of churches, temples, and other settings for worship, but not all of the residents of our great state identify as religious.

In fact, it may come as a surprise to you that one major Colorado city is in the top ten of the least religious cities in the entire country.

Denver Colorado is One of the Least Religious in the United States

A new study found that of all the major cities across the United States, Denver, Colorado is the fifth least religious in the nation.

Granted, the study only included major cities, and it comes as no surprise that Colorado's second-largest city, Colorado Springs, didn't make the list at all.

According to the study, as of 2023, 29% of Denver's population identifies as not affiliated with any religion. In other words, 29% of the city's residents identify as either agnostic or atheist.
