Hattiesburg is a city in Mississippi, bisected by the county line between Forrest County (where it is the county seat) and Lamar County. The population was 45,989 in the 2010 census. It is the principal city of the Hattiesburg, Mississippi, Metropolitan Statistical Area which encompasses Forrest, Lamar and Perry counties.
Founded in 1882 by pioneer lumberman and civil engineer William H. Hardy, Hattiesburg was named in honor of Hardy's wife Hattie. The town was incorporated two years later with a population of 400. Hattiesburg's population first expanded as a center of the lumber and railroad industries, from which was derived the nickname "The Hub City." It now attracts newcomers to the area because of the diversity of the economy, strong neighborhoods and the central location in South Mississippi.
