Super Bowl XLIX was an American football game between the American Football Conference (AFC) champion New England Patriots and National Football Conference (NFC) champion Seattle Seahawks to decide the National Football League (NFL) champion for the 2014 season. The Patriots defeated the Seahawks 28-24. The game was played on February 1, 2015, at University of Phoenix Stadium in Glendale, Arizona. This was the second Super Bowl played in that stadium (XLII), and the third one held in the Phoenix metropolitan area (XXX at Sun Devil Stadium in Tempe). The game was live broadcast in the United States by NBC.

For the second season in a row, but only the third time in 21 seasons, the number one seed from each conference met in the league championship game. This was the first time in a decade that an NFL team played in consecutive Super Bowl games, with the last such instance in 2004 and 2005, when the Patriots played in Super Bowls XXXVIII and XXXIX, respectively. Super Bowl XLIX was the Seahawks' second consecutive Super Bowl appearance, having defeated the Denver Broncos 43-8 in Super Bowl XLVIII in 2014, while the New England Patriots returned for their eighth Super Bowl appearance, and their first since losing 21-17 to the New York Giants in Super Bowl XLVI in 2012. With their appearance in Super Bowl XLIX, the New England Patriots joined the Dallas Cowboys and the Pittsburgh Steelers as one of the three teams that collectively share the record for most all-time Super Bowl appearances, as each has appeared in eight separate Super Bowls to date.
