2013 Seattle Seahawks season

The 2013 season was the Seattle Seahawks' 38th in the National Football League (NFL) and their fourth under head coachPete Carroll. With the Seahawks tenth win in the eleventh week of the season, the team secured double-digit victories in consecutive seasons for the first time in franchise history. Their 13–3 regular season record is tied with the 2005 season for the second best in franchise history. Seattle's defense in 2013 is regarded by many to be one of the best in NFL history.

The Seahawks clinched the NFC's No. 1 seed and homefield advantage throughout the playoffs with their 13–3 record. The Seahawks defeated the New Orleans Saints 23–15 in the Divisional round and the San Francisco 49ers 23–17 in the NFC Championship. In Super Bowl XLVIII, they defeated the Denver Broncos 43–8 for their first Super Bowl victory in franchise history. Eight of Seattle's wins were by double digits. The Seahawks allowed just 14.4 points per game in the regular season, which is a team record. The defense led the league in points allowed (231), yards allowed (4,378), and takeaways (39), the first team to lead all three categories since the 1985 Chicago Bears. The Seahawks outscored their opponents by 186 points, which was a team record until the Super Bowl LX-winning2025 team came around, outscoring their opponents by 191.

The 2013 Seahawks rank #18 on the 100 greatest teams of all time presented by the NFL on its 100th anniversary.
