The 2008 Seattle Seahawks season was the franchise's 33rd season in the National Football League (NFL), the seventh season in Qwest Field, and the tenth and final under head coach Mike Holmgren. The Seahawks' streak of four consecutive NFC West divisional championships was broken, as they fell to a 4–12 record and missed the playoffs for the first time since 2002.

Lumen Field is a multi-purpose stadium in Seattle, Washington, United States. Located in the city's SoDo neighborhood, it is the home field for the Seattle Seahawks of the National Football League (NFL), Seattle Sounders FC of Major League Soccer (MLS), and Seattle Reign FC of the National Women's Soccer League (NWSL). Originally called Seahawks Stadium, it was renamed Qwest Field in June 2004 when telecommunications carrier Qwest acquired the naming rights. The stadium became known as CenturyLink Field following Qwest's June 2011 acquisition by CenturyLink and was nicknamed "The Clink" as a result; it received its current name in November 2020 with CenturyLink's rebrand to Lumen Technologies. It is a modern facility with views of the Downtown Seattle skyline and a seating capacity of 68,740 spectators for NFL games and 37,722 for most MLS matches. The complex also includes the Event Center which is home to the Washington Music 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 Downtown Seattle, the stadium is accessible by multiple freeways and forms of mass transit.
