Decatur is a city in, and the county seat of, DeKalb County, Georgia, which is part of the Atlanta metropolitan area. With a population of 20,148 in the 2013 census,^[3] the municipality is sometimes assumed to be larger since multiple ZIP Codes in unincorporated DeKalb County bear Decatur as the address. The city is served by three MARTA rail stations (Decatur, East Lake, and Avondale). The city is located approximately 5 miles northeast of downtown Atlanta and shares its western border with both the city of Atlanta (the Kirkwood neighborhood) and unincorporated DeKalb County. The Druid Hills neighborhood is to the northwest of Decatur.

Decatur was established at the intersection of two Native American trails:  the Sandtown, which led east from the Chattahoochee River at Utoy Creek, and the Shallowford, which follows today's Clairmont Road, and eventually crossed near Roswell. It was named for United States Navy Commodore Stephen Decatur.

During the American Civil War, Decatur became a strategic site in Sherman's Atlanta Campaign. In July 1864, Major-General James McPherson occupied the town to cut off the Confederates' supply line from Augusta. On July 22, during the Battle of Atlanta, Confederate cavalry under Major-General Joseph Wheeler attacked McPherson's supply wagons and the Union troops left to defend the wagons. A historical marker at the old courthouse marks the site of this skirmish.

In the last half of the twentieth century the metropolitan area of Atlanta expanded into unincorporated DeKalb County, eventually surrounding two sides of the town of Decatur. Concurrently many well-to-do and middle class white Americans fled the area to more distant suburbs. The 1960s and 1970s witnessed dramatic drops in property values. However, more recently the city has regained economic vigor, partially thanks to several long-term downtown development plans that have come to fruition, making Decatur a trendy small mixed-use district with easy transit to downtown Atlanta. Over the past twenty years, it has gained a local and national reputation as a progressive city with a high level of citizen involvement that retains a small town feel despite its proximity to Atlanta.
