Greenwood is a city in Johnson County, Indiana, United States. The population was 49,791 at the 2010 Census, and increased to 54,491 in the Census 2014 estimates. It is home to the Greenwood Park Mall. Greenwood is located between Indiana State Road 37 and Interstate 65. The city shares a border with Indianapolis and is the most populous suburb in the southern portion of the Indianapolis Metropolitan Area.
The first inhabitants of the area currently known as Greenwood were the Delaware Indians (Lenape), but by 1813, Kentucky and Indiana militias dispersed or killed all the Delaware Indians in the area. Greenwood was then first known as "Smocktown" or "Smock's Settlement", and it became "Greenfield" in 1825. Since this clashed with another Greenfield located in Hancock County, the name of the settlement was changed to Greenwood. Some claim the town's name was in honor of Samuel Greenwood, who platted the community in 1872.
Greenwood was incorporated as a town under Indiana law in 1864 and became a fifth-class city in 1960.
Greenwood Commercial Historic District was listed on the National Register of Historic Places in 1991.
