Super Bowl XIX was an American football game between the American Football Conference (AFC) champion Miami Dolphins and the National Football Conference (NFC) champion San Francisco 49ers to decide the National Football League (NFL) champion for the 1984 season. The 49ers defeated the Dolphins by the score of 38–16, to win their second Super Bowl. The game was played on January 20, 1985, at Stanford Stadium, on the campus of Stanford University in Stanford, California, the first Super Bowl played in the San Francisco Bay Area. This also became the second Super Bowl after Super Bowl XIV where the game was coincidentally played in the home market of one of the participants.

The 1984 NFL season was the 65th regular season of the National Football League. The Colts relocated from Baltimore, Maryland, to Indianapolis, Indiana, before the season.
