Ohio County, County administrative division in southeastern Indiana, United States.
Ohio County covers 87 square miles along the Ohio River and functions as part of the Cincinnati metropolitan area, with Rising Sun serving as its county seat. The land is shaped by the river valley and its connections to the broader regional economy.
The county was established in 1844 when it separated from Dearborn County, following legislative action to resolve a dispute between Rising Sun and Lawrenceburg over which town should be the county seat. This division allowed Rising Sun to become its own regional administrative center.
The county is organized into four townships—Cass, Pike, Randolph, and Union—each maintaining its own local services and community identity. This structure shapes how people in different areas organize their daily lives and local affairs.
The Rising Sun/Ohio County Convention and Visitors Bureau provides information about local attractions, accommodations, and river-based activities for visitors exploring the area. Staff there can guide you to various points of interest throughout the county.
The county courthouse, built in 1845 with Greek Revival architecture and Doric pillars, is Indiana's oldest continuously operating judicial building. The structure remains in active use today and anchors the community's civic center.
