The Seattle Seahawks are a professional American football team based in Seattle, competing in the NFL's NFC West and playing their home games at Lumen Field since 2002. Founded as an expansion team in 1976, the Seahawks are famous for their passionate "12s" fanbase, who set a Guinness World Record for the loudest crowd noise in 2013.

The franchise achieved its most significant success in the 2010s under head coach Pete Carroll and their dominant "Legion of Boom" defense. This era culminated in their first and only Super Bowl victory, a commanding win over the Denver Broncos at Super Bowl XLVIII, following appearances in Super Bowls XL and XLIX. Notably, the Seahawks are the only NFL team to have played in both the AFC and NFC Championship Games, securing 12 division titles and three conference championships. The team also boasts several Pro Football Hall of Famers, including legendary receiver Steve Largent, recognizing their rich history and impact on the league.
