The following is an alphabetical listing of cities, towns, and villages in Isabella County:
Many population places have several names that they were known by. Often, especially in Northern Michigan where the population was sparse and isolated, towns were named after places the people came from in southern Michigan, or their home state. When a post office was established another name was given to avoid mailing confusion. Places may also have been known by a prominent landmark, such as a saloon, hotel or sawmill. Towns and villages were often named after the person who first platted the land, and then later changed. In the 1870's railroad stations became local meeting places and appeared on plat maps as population centers. The railroad station served as a shipping and commerce point for the local area.
