Circle dance, or chain dance, is a style of social dance done in a circle, semicircle or a curved line to musical accompaniment, such as rhythm instruments and singing, and is a type of dance where anyone can join in without the need of partners. Unlike line dancing, circle dancers are in physical contact with each other; the connection is made by hand-to-hand, finger-to-finger or hands-on-shoulders, where they follow the leader around the dance floor. Ranging from gentle to energetic, the dance can be an uplifting group experience or part of a meditation.

Being probably the oldest known dance formation, circle dancing is an ancient tradition common to many cultures for marking special occasions, rituals, strengthening community and encouraging togetherness. Circle dances are choreographed to many different styles of music and rhythms. Modern circle dance mixes traditional folk dances, mainly from European or Near Eastern sources, with recently choreographed ones to a variety of music both ancient and modern. There is a growing repertoire of new circle dances to classical music and contemporary songs.
