Oireachtas Rince na Cruinne (English: The Irish Dancing World Championships; often simply the Worlds) is an annual Irish stepdance competition run by An Coimisiún Le Rincí Gaelacha (the Irish Dancing Commission). The Worlds include competitions for solo stepdance, organised by gender and age; and for certain traditional and original ceili dances, also divided by age group and team gender composition. Oireachtas Rince na Cruinne is the top competition of the hierarchical system operated by An Coimisiún, and dancers must qualify at major Irish stepdance events across the world in order to compete.
