Qwest Field (pronounced IPA-en?kw?st) is a multi-purpose stadium in Seattle, Washington, United States. It serves as the home field for the Seattle Seahawks of the National Football League (NFL) and Seattle Sounders FC of Major League Soccer (MLS). It was originally called Seahawks Stadium but was renamed in June 2004 when the telecommunications carrier Qwest acquired naming rights. The complex also includes the Event Center with the WaMu Theater, a parking garage, and a public plaza. The venue hosts concerts, trade shows, and consumer shows along with sporting events. Located within a mile (1.6 km) of Seattles central business district, the venue is accessible by multiple freeways and forms of mass transit.

The stadium was built between 2000 and 2002 after voters approved funding for the construction in a statewide election held on June 17, 1997. This vote created the Washington State Public Stadium Authority to oversee public ownership of the venue. The owner of the Seahawks, Paul Allen, formed First & Goal Inc. to develop and operate the new facilities. Allen was closely involved in the design process and emphasized the importance of an open-air venue with an intimate atmosphere. The stadium is a modern facility with views of the nearby Seattle area. The stadium can seat 67,000 people.

The crowd at Qwest Field is notoriously loud during Seahawks games. The noise has contributed to the teams home field advantage (Home advantage) with an increase in false start (movement by an offensive player prior to the play) penalties against visiting teams.cite news first=John last=Branch title=For N.F.L., Crowd Noise Is a Headache date=September 9, 2004 url = work = The New York Times page =1accessdate=November 14, 2009 The stadium was the first in the NFL to implement a FieldTurf artificial field (artificial turf).
