Polka is a dance and genre of dance music originating in nineteenth-century Bohemia, now part of the Czech Republic. Though associated with Czech culture, polka is popular throughout Europe and the Americas.

Dance is an art form, often classified as a sport, consisting of sequences of body movements with aesthetic and often symbolic value, either improvised or purposefully selected. Dance can be categorized and described by its choreography, by its repertoire of movements or by its historical period or place of origin. Dance is typically performed with musical accompaniment, and sometimes with the dancer simultaneously using a musical instrument themselves.
