The 2018 season was the Seattle Seahawks' 43rd in the National Football League 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 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.
This was the first season since 2011 that the team did not feature the original Legion of Boom defensive unit and did not have Richard Sherman on the roster, as he was released on March 9 and signed with division rival San Francisco 49ers. Michael Bennett, another longtime Seahawk, was traded to the Philadelphia Eagles on March 7. His fellow defensive lineman Cliff Avril was released by the team on May 4. It was also the first season since 2009 that Kam Chancellor was not on the roster; he announced his retirement on July 1 due to the neck injury he sustained in Week 10 of the previous season.
On August 20, longtime Seahawks punter Jon Ryan was released from the team. He was the last remaining player from the team before coach Pete Carroll took over in 2010. With his release, the Seahawks shifted the punting duties to their fifth-round rookie Michael Dickson, who went on to make the Pro Bowl and was named First-team All-Pro.
This season is notable for featuring the NFL's first player with only one hand, as the Seahawks drafted Shaquem Griffin in the fifth-round of the 2018 NFL Draft out of the University of Central Florida. He is the twin brother of Seahawks cornerback Shaquill Griffin.
Paul Allen, who had owned the team since 1997, died of cancer on October 15, at the age of 65. In tribute, the team wore patches labeled "PGA" for the rest of the season beginning at the game against the Detroit Lions.
