Oregonia is an unincorporated community in northwestern Washington Township, Warren County, Ohio, United States,[1] on the east shore of the Little Miami River about five miles northeast of Lebanon and six miles south of Waynesville.
A post office called Oregon was established in 1846, and the name was changed to Oregonia in 1882.
Bikers, hikers, and canoers often stop at the market or a restaurant along the trail which follows the river on the former train route.
In October of each year, the "Devils Staircase" motorcycle hill climb is held on a hill just south of the main settlement.
