Hopak, also spelled "Gopak," is a lively Ukrainian folk dance characterized by its energetic and vigorous movements. It originated among the Ukrainian Cossacks, a group of military communities in Ukraine and southern Russia, and is often performed as a solo dance or as part of a larger group.

Hopak is known for its athletic and acrobatic elements, with dancers executing high jumps, kicks, and spins. The dance is typically accompanied by fast-paced, upbeat music, often featuring instruments like the accordion, violin, and drums.

In traditional performances, dancers wear colorful and elaborate costumes that reflect Ukrainian culture and heritage. The dance itself is a celebration of strength, agility, and Ukrainian identity, and it remains popular in both traditional folk settings and modern interpretations of Ukrainian dance.
