Greenfield is a city in and the county seat of Hancock County, Indiana, United States, and a part of the Indianapolis metropolitan area. The population was 20,602 at the 2010 census, and an estimated 23,006 in 2019. It lies in Center Township.

Greenfield was a stop along the Pittsburgh, Cincinnati, Chicago and St. Louis Railroad that connected Pittsburgh to Chicago and St. Louis.


Hancock County was created on March 1, 1828, and named for John Hancock, the first person to sign the Declaration of Independence. The town of Greenfield was chosen as the county seat on April 11, 1828. The Commissioners announced, "The seat of Justice of Hancock County shall be known and designated by the name and title of Greenfield." The population of the county at that time was 400.

Early settlers built along the two creeks which flow south through Center Township, which includes Greenfield. The first businesses were small grist mills for grinding corn and wheat for settlers.

U.S. Route 40, the National Road, was built through Hancock County around 1835. It was heavily traveled by wagon trains going west and livestock going to Cincinnati. In 1853, the first steam railroad was completed by the Indiana Central Railroad at the south edge of Greenfield. The railroad became part of the Pennsylvania Railroad System and later the Penn-Central. These tracks were removed in the 1980s.

During this time, Greenfield's population continued to grow. Greenfield was incorporated as a city in 1876 with a population of 2,023. The greatest single period of growth began in 1887 when natural gas was discovered in the area. Greenfield was a boom town for 20 years, with the founding of manufacturing plants and other industries.

A statue of James Whitcomb Riley, which stands in front of the Hancock County Courthouse, was erected in 1918. It was purchased with money donated by school children from all over the United States. Each year, during the Riley Festival in October, the city's school children parade to the statue to place flowers around it.

Charles Barr House, Greenfield Courthouse Square Historic District, Greenfield Residential Historic District, Lilly Biological Laboratories, Lincoln Park School, and James Whitcomb Riley House are listed on the National Register of Historic Places.
