The 49ers–Seahawks rivalry is a rivalry between the San Francisco 49ers and Seattle Seahawks in the National Football League (NFL). The Seahawks currently lead the all-time series record 18–15, including 1–0 in the playoffs.
The two teams were not rivals until 2002, when the Seahawks returned to the NFC for the first time since their inaugural 1976 season. Prior to 2002, the 49ers led the all-time series 4–2, but since they became NFC West divisional rivals in 2002, the Seahawks lead the series 14–11. Originally, the rivalry was rather lopsided, as the Seahawks won 8 out of 12 meetings from 2002–2007. Since 2008, the 49ers have competed against the Seahawks with more fire power, with a record of 6–4 since then. The rivalry was once considered not very significant, due to the two teams having little history against each other and with both suffering significant stretches of mediocrity. For example, while the Seahawks won four straight division titles from 2004–2007, the 49ers finished in third or fourth place each season and did not have a winning season from 2003–2010. Likewise, the Seahawks suffered four straight losing seasons from 2008–2011. Despite their stretch of mediocrity, the Seahawks have remained competitive in games against the 49ers in those years, especially games at CenturyLink Field, where their worst loss to the 49ers there was by only ten points in 2006. Currently, 2006 and 2011 are the only seasons in which the 49ers have swept a season series with the Seahawks, whereas the Seahawks have swept a season series with the 49ers five times.
The rivalry intensified in 2011, when long-standing college rival coaches — former USC coach Pete Carroll and former Stanford coach Jim Harbaugh — took over as head coaches, with Carroll becoming the Seahawks' coach in 2010, and Harbaugh becoming the 49ers coach the following season. Both teams drafted young, mobile quarterbacks to lead their franchises, Seattle's Russell Wilson and San Francisco's Colin Kaepernick. Both coaches turned their respective franchises into perennial playoff contenders, and since 2010, either the Seahawks or the 49ers have claimed the NFC West championship.
Since Russell Wilson became the starter for Seattle in the 2012 season, the 49ers have been outscored 130-58 in the regular season.
The two teams met in the 2014 NFC Championship Game in CenturyLink Field with a trip to Super Bowl XLVIII on the line, with the Seahawks winning by a score of 23–17. The game ended when Seahawks' cornerback Richard Sherman, whom Jim Harbaugh previously coached at Stanford, tipped an end zone pass that led to a game-ending interception. Seattle went on to defeat the Denver Broncos 43–8 in Super Bowl XLVIII to win their first Super Bowl championship. San Francisco had represented the NFC in a losing effort in Super Bowl XLVII the previous season.
