Hopak (Ukrainian: гопа́к, IPA: [ɦoˈpɑk]) is a Ukrainian folk dance originating as a male dance among the Zaporozhian Cossacks, but later danced by couples, male soloists, and mixed groups of dancers. It is performed most often as a solitary concert dance by amateur and professional Ukrainian dance ensembles, as well as other performers of folk dances. It has also been incorporated into larger artistic opuses such as operas, ballets and theatre.
