Blackford County is located in the east central portion of the U.S. state of Indiana. The county is named for Judge Isaac Blackford, who was the first speaker of the Indiana General Assembly and a long-time chief justice of the Indiana Supreme Court. Created in 1838, Blackford County is divided into four townships, and its county seat is Hartford City. Two incorporated cities and one incorporated town are located within the county. The county is also the site of numerous unincorporated communities and ghost towns. Occupying only 165.58 square miles (428.9 km2), Blackford County is the fourth smallest county in Indiana. As of the 2010 census, the county's population was 12,766 people in 5,236 households. Based on population, the county is the 8th smallest county of the 92 in Indiana. Although no interstate highways are located in Blackford County, three Indiana state roads cross the county, and an additional state road is located along the county's southeast border. The county has two railroad lines. A north–south route crosses the county, and intersects with a second railroad line that connects Hartford City with communities to the west.
Hartford City is a city in the U.S. state of Indiana, and the county seat of Blackford County. Located in the northeast central portion of the state, the small farming community experienced a 15-year “boom” beginning in the late 1880s. The Indiana Gas Boom was caused by the discovery of natural gas in the area, and it caused the community to transition from an agricultural economy to one that also included manufacturing. The boom brought residents, retail establishments, and craftspeople. The increased population meant construction of new roads, schools, and churches. After the boom came a long period of growth and stability. Agriculture remained as the fundamental industry.

Renner is an extinct American village in Indiana's Blackford County. Although Renner has been listed as a “populated place” by the U.S. Geological Survey, this description is misleading. Renner was a railroad stop on the Pittsburgh, Cincinnati and St. Louis Railroad. The land around the railroad stop was originally used to supply timber for railroad crossties, and eventually became a livestock farm. Housing for the families of the employees of the livestock farm was also located nearby. Although it is not known for certain, Renner is thought to have been named for railroad executive John W. Renner. Renner was an executive of the Pittsburgh, Cincinnati and St. Louis Railroad, and later the Pennsylvania Railroad, and retired with over 50 years of railroad experience. Another community, Rennerdale, Pennsylvania, was named in his honor in 1895.
