Swing dance is a group of social dances that developed with the swing style of jazz music in the 1920s–1940s, with the origins of each dance predating the popular "swing era". Hundreds of styles of swing dancing were developed; those that have survived beyond that era include Charleston, Balboa, Lindy Hop, and Collegiate Shag. Today, the best-known of these dances is the Lindy Hop, which originated in Harlem in the early 1930s. While the majority of swing dances began in African-American communities as vernacular African-American dances, some influenced swing-era dances, like Balboa, developed outside of these communities.

Social dances are dances that have social functions and context. Social dances are intended for participation rather than performance. They are often danced merely to socialise and for entertainment, though they may have ceremonial, competitive and erotic functions.
