Riverside and Avondale are two adjacent and closely associated neighborhoods, alternatively considered one continuous neighborhood, of Jacksonville, Florida. The area is primarily residential, but includes some commercial districts, including Five Points, the King Street District, and the Shoppes of Avondale.
Riverside was first platted in 1868 and was annexed by Jacksonville in 1887. Its greatest growth occurred between the Great Fire of 1901 and the failure of the 1920s Florida land boom; this period included the creation of the original Avondale development in 1920. Today, Riverside and Avondale are notable for their particularly diverse architecture and their emphasis on planning and historic preservation, which have made them Florida’s most architecturally varied neighborhood. Both neighborhoods are listed as National Register Historic Districts.
