The Joffrey Ballet, based in Chicago, Illinois, is one of the world's premier dance companies. The Joffrey regularly performs classical ballets, including Romeo & Juliet and The Nutcracker, and modern dance pieces. Many choreographers have worked with the Joffrey, including Paul Taylor, Twyla Tharp, George Balanchine, and founders Gerald Arpino and Robert Joffrey. Founded as a touring company in 1956, it was based in New York City until 1995 when it moved to Chicago. The company's headquarters and dance academy are in Joffrey Tower, and it performs its October–May season at the Auditorium Theatre. In 2020 the company will move its presentation venue to the Civic Opera House through an arrangement with the Lyric Opera of Chicago.
