The 1989 Sunkist Fiesta Bowl, played on Monday, January 2, was the 18th edition of the Fiesta Bowl. It featured the top-ranked Notre Dame Fighting Irish and the third-ranked West Virginia Mountaineers. With both teams undefeated, the Fiesta Bowl was the stage for the "national championship" for the second time in three years. As in 1987, the Fiesta Bowl featured two independents squaring off for the national title.
