1980 New Orleans Saints season

The 1980 New Orleans Saints season was the team's 14th as a member of the National Football League (NFL). The Saints failed to improve on the previous season's record of 8–8, instead winning only one game. The team missed the playoffs for the fourteenth consecutive season and had the dubious distinction not only of winning only a single game, but winning it by a single point against the New York Jets, who like the Saints had widely been predicted before the season to advance to the playoffs, but struggled instead. The main culprit of the Saints' collapse was the defense, which ranked last in yards and points (487) allowed.

The team's only bright spot was tenth-year quarterback Archie Manning, who proceeded to have the best year of his career, throwing for 3,716 yards, 23 touchdowns and 20 interceptions.
