Victor Kal is the stage name of Czech rapper, singer, and producer Viktor Kalián.

Tracks like "víno," "BOYBAND," "NAVŽDYCKY BLÁZEN," "ZÁKAZ VSTUPU," and "3BRA3" exemplify his signature sound – minimalist yet evocative production paired with candid, emotionally charged lyrics sung or rapped in Czech.
