Yiannis Chryssomallis (Greek: Γιάννης Χρυσομάλλης, Giánnis Chrysomállis; born November 14, 1954), known professionally as Yanni (/ˈjɑːni/ YAH-nee), is a Greek pianist, keyboardist, composer, and music producer who has spent his adult life in the United States.

Yanni continues to use the musical shorthand that he developed as a child, blending jazz, classical, soft rock, and world music to create predominantly instrumental works. As this genre of music was not well suited for commercial pop radio and music television, Yanni achieved international recognition by producing concerts at historic monuments and by producing videos that were broadcast on public television. His breakthrough concert, Yanni Live at the Acropolis, yielded the second best-selling music video of all time. Additional historic sites for Yanni's concerts have included India's Taj Mahal, China's Forbidden City, the United Arab Emirates' Burj Khalifa, Russia's Kremlin, Puerto Rico's El Morro castle, Lebanon's ancient city of Byblos and Tunisia's Roman Theatre of Carthage.
