Clarkston is a city in DeKalb County, Georgia, United States. The population was 7,554 as of the 2010 census. The Clarkston Campus of Georgia State University's Perimeter College is just south of the city limits.
The city is noted for its ethnic diversity, and is often referred to as "the most diverse square mile in America" and "the Ellis Island of the South." In the 1990s, refugee resettlement programs identified Clarkston as a good fit for displaced persons of many backgrounds. The rental market was open, residents were moving farther out from the Atlanta urban core, and Clarkston was the last stop on a transit line into the city. At present students attending Clarkston High School come from over 50 different countries; the local mosque (Masjid al-Momineen, or Mosque of the Faithful in English) has a diverse and sizable congregation; and over half the population is estimated by some to be foreign born.
A post office called Clarkston has been in operation since 1876. The Georgia General Assembly incorporated the place in 1882 as the "Town of Clarkston", with municipal corporate limits extending in a one-half mile radius from the Georgia Railroad depot. The community was named after W. W. Clark, a railroad official.
