Wilmington, Ohio at a glance: county seat and college town
By LeaAnn Taylor · October 29, 2026 · 5 min read
Wilmington is the kind of town that rewards a closer look. It is the county seat and largest city of Clinton County, Ohio, home to about 12,600 people who share downtowns, parades, and front-porch waves. It is also the only city in the county that can claim a 150-year-old college, a century-old theater, and a dessert credited to a local pharmacist, all within a few blocks of each other.
The Quaker County of Ohio
Clinton County was founded in 1810 and was long known as the "Quaker County of Ohio," a legacy that still shapes the place. In 1870, local Quakers bought an unfinished building at auction and started what became Wilmington College, a private liberal arts college affiliated with the Religious Society of Friends. Its students compete as the Quakers in NCAA Division III, and the campus has been part of town life ever since: concerts, athletics, and a steady stream of young energy on the sidewalks.
A few friendly bragging rights
Two hometown claims travel well. The banana split is said to have been invented here in 1907 at Hazard's Drug Store by pharmacist Ernest R. Hazard, a story the city celebrates each June with the Banana Split Festival. And the Murphy Theatre, opened on Main Street in 1918, still draws crowds for performances and films a century later.
The town also has an industrial twist: Wilmington Air Park was once the U.S. hub for Airborne Express and later DHL, and it has been redeveloped as an industrial air park that still shapes local jobs and logistics.
"About an hour from three of the biggest cities in Ohio, and light-years from city traffic."
Squarely in the middle of Ohio
Wilmington sits roughly equidistant from Columbus, Cincinnati, and Dayton, each about an hour's drive away. For commuters, that is a real advantage: big-city jobs, small-town evenings. For everyone else, it means day trips in any direction: cinemas and museums north, the river and hills south, festivals in every season.
Where to go from here
This snapshot is just the opening page of the guide. In the coming weeks we will keep profiling neighborhoods, parks, and the people who make Wilmington work. If you are new to town, or thinking of moving here, the best next step is the same one we recommend to everyone: take a walk down Main Street, and then come say hello.
