Bell is a census-designated place (CDP) in Adair County, Oklahoma, United States.

[3] According to the United States Census Bureau, the CDP has a total area of 22.2 square miles (57 km2), all land.

In the early 1980s, the Cherokee Nation, under the direction of Wilma Mankiller (then the director of the Cherokee Nation Community Development Department, later principal chief) and her colleague (and future husband) Charlie Soap, put together a project to build a 16-mile waterline to Bell, where many of the residents still had no indoor plumbing.

The tribe provided equipment and technological assistance, while Bell residents contributed most of the labor on a volunteer basis.

The project drew widespread attention and launched Mankiller's political career.
