The 1980 Seattle Seahawks season was the team's fifth season in the National Football League (NFL). The 1980 season was a strange season for the Seattle Seahawks. The team started off 4–3, then lost the remaining nine games of the season. They accumulated four road wins, but lost all eight regular season home games. The offense struggled, especially after losing Sherman Smith to a knee injury for the season. With the running game struggling, the team gave up 52 sacks, up from 23 in 1979. The offense went from 7th to 21st. Even though the defense improved from 27th to 13th, the Seahawks still gave up 405 points.
