Richland County is a county located in the U.S. state of Ohio. As of the 2010 census, the population was 124,475.  Its county seat is Mansfield.  The county was created in 1808 and later organized in 1813.  It is named for the fertile soil found there. 
Richland County is included in the Mansfield, OH Metropolitan Statistical Area as well as the Mansfield- Ashland- Bucyrus, OH Combined Statistical Area. The county is one of the six Metropolitan Statistical Areas that make up Northeast Ohio and is also included in the Cleveland- Akron, OH Combined Statistical Area.
At its formation in 1806 Richland County encompassed a larger area. The land was mainly forest. Settlers cleared the land for farming and the population increased. In 1846, some eastern portions of the county (such as Green Township) were separated to contribute to formation of Ashland County.
