The 2018 season was the Seattle Seahawks' 43rd in the National Football League (NFL) and their ninth under head coach Pete Carroll. The Seahawks improved on their 9–7 record from the 2017 season, finishing 10–6, the sixth time in seven years that they recorded at least ten wins in a season. They also played in London for the first time in franchise history, defeating the Oakland Raiders 27–3 in Week 6. With a win over the Kansas City Chiefs and eventual league MVP Patrick Mahomes in Week 16, the Seahawks returned to the playoffs; their seventh appearance in the nine seasons under Carroll. However, the Seahawks suffered their first one-and-done postseason campaign since 2004, as they fell to the Dallas Cowboys in the Wild Card round 22–24.
