The 1988 Seattle Seahawks season was the team's 13th season with the National Football League (NFL). The Seahawks won their first division title in the AFC West. They won the division with only a 9–7 record and finished with only a +10-point differential. The team never went under .500 during the season and clinched the AFC West in week 16 with a 43–37 shootout win over the Los Angeles Raiders. The Seahawks were the #3 seed in the AFC playoffs; they lost 21–13 on the road in the Divisional round to the top-seeded Cincinnati Bengals on December 31. In late August, Ken Behring and partner Ken Hofmann purchased the team from the Nordstrom family for $80 million.
