The 1984 New Orleans Saints season was the team's 18th as a member of the National Football League. They were unable to improve on their previous season's output of 8–8, winning only seven games. The team failed to qualify for the playoffs for the eighteenth consecutive season. The Saints started out winning four of their first five games. However, the Saints would struggle as newly acquired Quarterback Richard Todd threw 19 interceptions to just 11 touchdowns as the Saints again finished the season with a losing record at 7-9.
Todd was acquired from the New York Jets for a first-round draft choice, and he beat out the aging Ken Stabler for the starting job at training camp, the Saints' last at Vero Beach, Florida. Stabler, who was inducted into the Pro Football Hall of Fame in 2016, retired midway through the season.
Late in the season, owner John Mecom Jr., who purchased the Saints as an expansion franchise for $8.5 million in late 1966, announced he would sell the team, with an asking price of $70 million. Fears abounderd across Louisiana the team would be moved to Jacksonville if Mecom could not find a local buyer. Eventually, the team was sold in early 1985 to New Orleans native and car magnate Tom Benson, with Louisiana Governor Edwin Edwards brokering the deal.
