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.
The Redskins entered the game as the defending Super Bowl XVII champions, finished the 1983 regular season with a league-best 14–2 record, led the league in fewest rushing yards allowed, and set a then-NFL record in scoring with 541 points. The Raiders posted a 12–4 regular-season record in 1983, their second in Los Angeles, having moved there from Oakland in May 1982.
