Coloradan is the preferred term for a person from Colorado, while Coloradoan is also an established alternative. Both words are used to describe someone who lives in or comes from the U.S. state of Colorado.
People often search for Coloradan or Coloradoan because the two forms look almost identical. The only visible difference is the extra o in Coloradoan. That small difference can make it hard to know which form belongs in formal writing, news articles, school assignments, or everyday English.
The confusion is understandable because both forms have appeared in published English for many years. Coloradoan is also found in the name of The Coloradoan, a newspaper based in Fort Collins. At the same time, Coloradan is the form used by the University of Colorado Boulder for its alumni magazine and is listed by Cambridge as the main form, with Coloradoan as an alternative.
This guide explains the meaning, history, spelling, usage, and regional differences between Coloradan and Coloradoan. You will also learn which form to use in formal and everyday writing.

Definition and Meaning of Coloradan or Coloradoan
What Does Coloradan Mean?
Coloradan is a noun for a native or resident of Colorado.
It can also work as an adjective meaning relating to Colorado or its people. Cambridge gives both noun and adjective uses for the word.
For example:
Maria is a Coloradan.
Here, Coloradan is a noun. It tells us that Maria is from Colorado or lives there.
As an adjective:
The museum features Coloradan history.
Here, the word describes something connected with Colorado.
What Does Coloradoan Mean?
Coloradoan has the same basic meaning.
It can refer to a person from Colorado or describe something connected with the state or its people. Cambridge lists it as an alternative to Coloradan.
For example:
He is a lifelong Coloradoan.
The meaning is clear. The main difference is the form of the word.
Coloradan vs Coloradoan in Simple English
The difference can be reduced to one extra letter:
- Coloradan = a person from Colorado
- Coloradoan = a person from Colorado
The meaning is essentially the same.
The main issue is which form is preferred in a particular style or context.
The Origin of Coloradan or Coloradoan
Both words are demonyms. A demonym is a word used for people who live in, come from, or are associated with a particular place.
The basic structure is:
Colorado + -an
This produces the forms Coloradan and Coloradoan.
The debate is mainly about what happens to the final o in Colorado before the suffix is added.
Why Is It Coloradan?
The form Coloradan drops the final o from Colorado before adding -an.
This pattern is not unusual in English demonyms. The University of Colorado Boulder notes the English-language convention of dropping the final o from certain Spanish-origin place names before adding -an, giving San Franciscan as an example.
Why Is It a Coloradoan?
Coloradoan keeps the full place name and adds -an.
That makes the word easy to understand because the connection to Colorado remains fully visible.
Both forms have a long history of use. The University of Colorado Boulder explains that its own magazine adopted Coloradan in 1998, while its student yearbook had previously used Coloradoan before switching in the 1930s.
Which Form Became More Common?
Historical written-language evidence has favored Coloradan in more recent periods. The University of Colorado Boulder reported that Google Ngram data showed Coloradan surpassing Coloradoan in 1969 and remaining ahead through 2000, the end of the dataset discussed in that article.
This does not mean Coloradoans disappeared. It remains in dictionaries and real-world use.
British English vs American English Spelling
Coloradan and Coloradoan are primarily American geographic terms because they refer specifically to the U.S. state of Colorado.
There is no standard British-versus-American spelling rule that changes one form into the other.
| Meaning | British English | American English | Example |
| Person from Colorado | Coloradan | Coloradan | She is a Coloradan. |
| Alternative form | Coloradoan | Coloradoan | He is a Coloradoan. |
| Plural of Coloradan | Coloradans | Coloradans | Many Coloradans live in Denver. |
| Adjective | Coloradan | Coloradan | Coloradan history is diverse. |
The important point is that Coloradoan is not an American spelling of a British word. Instead, it is an alternative demonym.
Cambridge lists Coloradan as the main entry and Coloradoan as an alternative. It also gives both noun and adjective uses.
So, unlike pairs such as colour/color, there is no British-American spelling switch here.
Which Spelling Should You Use?
