|1980 Seattle Seahawks season|
|Head coach||Jack Patera|
|Division place||5th AFC West|
|Playoff finish||Did not qualify|
The 1980 Seattle Seahawks season was the team's fifth season in the National Football League.
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.
Memorable moments included a 26-7 win in Houston, intercepting Kenny Stabler five times; a 17-16 win in Kansas City (their last at Arrowhead Stadium until 1990); and a 14-0 win in Washington, with the offense rushing for over 220 yards.
More indicative of the season were the home losses: a week 1 34-13 rout at home inflicted by the Chargers, a 37-31 loss to the New England Patriots, featuring several lead changes, as the Seattle defense could not hold on; losing to the Kansas City Chiefs 31-30, after going into the 4th quarter with a 23-10 lead, and the Chiefs intercepting Jim Zorn a season-high five times, leading to 17 KC points. The low point of the season was a 27-21 loss to a struggling New York Giants team, one which finished 4-12 (although one was over the Cowboys). On Thanksgiving Day, November 27, the Dallas Cowboys defeated the Seahawks 51-7, in Dallas, but many people believe the Giants loss was worse.
The successes of the 1978 and '79 seasons were long forgotten by season's end.
