WCW/New Japan Supershow was an annual professional wrestling pay-per-view (PPV) jointly promoted by the Atlanta, Georgia based World Championship Wrestling (WCW) and the Japanese New Japan Pro Wrestling (NJPW) wrestling promotions. It was held in 1991, 1992 and 1993, and was promoted as "Starrcade" in Japan, but not billed as such in the United States due to WCW already having a show called "Starrcade" held each year in December. The show would be taped in Japan and then edited and aired in North America at a later date in WCW. The last two of this three events were also the two first January 4 Dome Show.
