Ohio County is a county located in southeastern Indiana. With a 2010 population of 6,128, and an area of just 87 square miles, Ohio County is the smallest county in Indiana in both area and population. The county seat and only incorporated municipality is Rising Sun. The county was officially established in 1844 and was one of the last Indiana counties to be created.
Ohio County borders the state of Kentucky across the Ohio River for which it was named. It is part of the Cincinnati, OH-KY-IN Metropolitan Statistical Area.
Dearborn County was formed from Indiana Territory in 1803, and its borders were modified several times, both before and after the creation of the state of Indiana in 1816. Ohio County was created out of Dearborn County, authorized by legislative action effective January 4, 1844 to resolve a dispute of county seat between Rising Sun and Lawrenceburg. It was named for the Ohio River, which defines its eastern border.
The Ohio County courthouse was built in the county seat of Rising Sun in 1845. It is a two-story Greek Revival brick building measuring about 60 feet (18 m) by 40 feet (12 m), including the portico supported by Doric pillars. This courthouse is still in use and is the oldest continuously-used courthouse in the state.
According to the 2010 census, the county has a total area of 87.43 square miles (226.4 km2), of which 86.14 square miles (223.1 km2) (or 98.52%) is land and 1.29 square miles (3.3 km2) (or 1.48%) is water.

The county government is a constitutional body granted specific powers by the Constitution of Indiana and the Indiana Code. The county council is the legislative branch of the county government and controls all spending and revenue collection. Representatives are elected from county districts. The council members serve four-year terms and are responsible for setting salaries, the annual budget and special spending. The council also has limited authority to impose local taxes, in the form of an income and property tax that is subject to state level approval, excise taxes and service taxes.
A board of commissioners serves as the county's executive body. The commissioners are elected county–wide to staggered four–year terms. One commissioner serves as board president. The board executes the acts legislated by the council, collects revenue, and manages day-to-day functions of the county government.
The county maintains a small claims court that can handle some civil cases. The judge on the court is elected to a term of four years and must be a member of the Indiana Bar Association. The judge is assisted by a constable who is elected to a four-year term. In some cases, court decisions can be appealed to the state level circuit court which is shared with neighboring Dearborn County.
The county has several other elected offices, including sheriff, coroner, auditor, treasurer, recorder, surveyor and circuit court clerk; they are elected to four–year terms. Members elected to county government positions are required to declare party affiliations and be residents of the county.
Each of the townships has a trustee who administers rural fire protection and ambulance service, provides poor relief and manages cemetery care, among other duties. The trustee is assisted in these duties by a three-member township board. The trustees and board members are elected to four-year terms.
