The 1998 Seattle Seahawks season was the franchise's 23rd season in the National Football League (NFL), the 23rd playing their home games at the Kingdome, and the fourth and final under head coach head coach Dennis Erickson. They matched their 8–8 record from 1997, but a late-season loss to the New York Jets came due to a controversial call when Jets quarterback Vinny Testaverde ran in a touchdown but was downed short of the goal line yet the play was ruled a touchdown; the loss helped knock Seattle to 6–7. They won the next two games but a loss to the Denver Broncos in the final week saw them finish 8–8 and out of the playoffs for the tenth consecutive season.
