Riverdance is a theatrical show that consists mainly of traditional Irish music and dance. With a score composed by Bill Whelan, it originated as an interval act during the Eurovision Song Contest 1994, featuring Irish dancing champions Jean Butler, Michael Flatley and the vocal ensemble Anúna. Shortly afterwards, husband and wife production team John McColgan and Moya Doherty expanded it into a stage show, which opened in Dublin on 9 February 1995. As of 2023, the show continues to tour the world.

Irish dance refers to a group of traditional dance forms that originate in Ireland, encompassing dancing both solo and in groups, and dancing for social, competitive, and performance purposes. Irish dance in its current form developed from various influences such as earlier native Irish dance, English country dancing and later possibly French quadrilles, as it became popular in Britain and Ireland during the 19th century. Dance was taught by "travelling dance masters" across Ireland in the 17th and 18th centuries, and separate dance forms developed according to regional practice and differing purposes. Irish dance became a significant part of Irish culture, particularly for Irish nationalist movements. From the early 20th century, a number of organisations promoted and codified the various forms of dance, creating competitive structures and standardised styles. Irish dancers who compete for competitive reasons dance in a dance style that is more modern than traditional Irish dance. It is mainly done solo, but there is some team dancing in groups of 2, 3, 4, 6, 8, 10, 16 and even numbers onwards.
