The 1983 Seattle Seahawks season was the team's 8th season with the National Football League (NFL). The 1983 season was the first season head coach Chuck Knox coached the team. It was also the first season in which the Seahawks made the AFC playoffs, where they won the first two postseason games in franchise history, before losing in the AFC Championship Game to the eventual Super Bowl champion Los Angeles Raiders 30–14. The AFC Championship game against the Raiders would be the only time the Seahawks would appear in the AFC Championship Game, as they failed to appear in one from 1984 to 2001, the rest of their time in the AFC. They would not reach a conference championship again until 2005, when they were in the NFC West. During the offseason, the Seahawks changed the color of the facemasks on their helmets from gray to blue.

Offseason

The Seattle Seahawks hired Chuck Knox, a coach capable of creating comebacks for teams. They also modified their uniforms, incorporating striping trim on the jersey collars, and incorprorating the Seahawks logo onto the jersey's sleeves. The TV numbers were moved from the jersey sleeves to the shoulders. The helmet facemasks became blue, and the socks lost their stripes and became all blue. The uniform would remain basically unchanged through the 2001 season.
