Southside (Jacksonville)

There are more than 500 neighborhoods within the area of Jacksonville, Florida, the largest city in the contiguous United States by area. These include Downtown Jacksonville and surrounding neighborhoods. Additionally, greater Jacksonville is traditionally divided into several major sections with amorphous boundaries: Northside, Westside, Southside, and Arlington, as well as the Jacksonville Beaches.

There are four municipalities within Duval County that are outside of Jacksonville's city limits: Baldwin, Atlantic Beach, Neptune Beach, and Jacksonville Beach. The latter three communities, all located on a coastal barrier island, form part of the area known as the Jacksonville Beaches, together with Mayport within the Jacksonville city limits and Ponte Vedra Beach in St. Johns County.

Jacksonville consolidated with Duval County in 1968; as such its city limits largely match the county borders. The City of Jacksonville estimates that there are over 500 neighborhoods within this area. In addition, the greater area of Jacksonville is often divided into several large sections with amorphous boundaries. The areas include both urban neighborhoods within the old city limits as well as further-out suburban and rural communities. Three have "directional" names, a common characteristic in geographical areas. The most commonly used vernacular areas are Northside, located north of Downtown; Arlington, east of Downtown across the St. Johns River; Southside, across the river from Downtown to the south, and Westside, to the west of Downtown. Additionally, the Jacksonville Beaches designates the group of towns and communities along the Atlantic coast.
