Super Bowl XVIII was an American football game played on January 22, 1984, at Tampa Stadium between the National Football Conference (NFC) champion and defending Super Bowl XVII champion Washington Redskins and the American Football Conference (AFC) champion Los Angeles Raiders to determine the National Football League (NFL) champion for the 1983 season. The Raiders defeated the Redskins, 38–9. The Raiders' 38 points scored and 29-point margin of victory broke Super Bowl records; it remains the most points scored by an AFC team in a Super Bowl, later matched by the Kansas City Chiefs in Super Bowl LVII. This is the first time the city of Tampa hosted the Super Bowl and was the AFC's last Super Bowl win until Super Bowl XXXII, won by the Denver Broncos.

Tampa Stadium was a large open-air stadium located in Tampa, Florida, which opened in 1967 and was significantly expanded in 1974–75. The facility is most closely associated with the Tampa Bay Buccaneers of the National Football League, who played there from their establishment in 1976 until 1997. It also hosted two Super Bowls, in 1984 and 1991, as well as the 1984 USFL Championship Game. To meet the revenue demands of the Buccaneers' new owners, Raymond James Stadium was built nearby in 1998, and Tampa Stadium was demolished in early 1999.
