The Budapest Opera Ball (Budapesti Operabál in Hungarian, Budapester Opernball in German) is an annual Hungarian society event taking place in the building of the Hungarian State Opera (Operaház) on the last Saturday of the carnival season, usually late February. By transforming the venue into a ballroom every year, the stage transforms into a cultural display.
