Okolona is an unincorporated community in southwestern Napoleon Township, Henry County, Ohio, United States. It has a post office with the ZIP code 43550.[1] It is located along County Road 17-D a short distance southeast of U.S. Route 24.
Okolona was originally called Oakland Station, and under the latter name had its start in the 1860s as a station on the Wabash Railroad.[2] There being another Oakland in the state, the town's name was changed to the invented name, by Nathaniel Norden, of Okolona in order to avoid repetition.[3] A post office called Okolona has been in operation since 1866 but has since been closed 2016.[4]
