The 1984 NFL season was the 65th regular season of the National Football League. The Colts relocated from Baltimore, Maryland to Indianapolis, Indiana before the season. The Colts new home field was the Hoosier Dome. The New York Jets moved their home games from Shea Stadium in New York City to Giants Stadium in East Rutherford, New Jersey.
The season ended with Super Bowl XIX when the San Francisco 49ers defeated the Miami Dolphins 38–16 at Stanford Stadium in California. This was the first Super Bowl televised by ABC, who entered into the annual championship game rotation with CBS and NBC. This game marked the second shortest distance between the Super Bowl host stadium (Stanford, California) and a Super Bowl team (San Francisco 49ers).
The 49ers became the first team in NFL history to win 15 games in a regular season and to win 18 in an entire season (including the postseason). Additionally, two major offensive records were set this season, with quarterback Dan Marino establishing a new single-season passing yards record with 5,084 (later broken by Drew Brees and Tom Brady in 2011 and by Peyton Manning in 2013), and Eric Dickerson establishing a new single-season rushing yards record with 2,105.
Also during the season, San Diego Chargers wide receiver Charlie Joiner became the all-time leader in career receptions; he set that mark in a game between the Chargers and the Pittsburgh Steelers at Pittsburgh's Three Rivers Stadium.
In a week 10 game against the Kansas City Chiefs the Seattle Seahawks set numerous NFL records for interception returns including most interception return yardage in a game and most interceptions returned for touchdowns in a game with 4 (all touchdowns over 50 yards in length). The Seahawks also tied an NFL record with 63 defensive takeaways on the season.

Major rule changes
- Linebackers are permitted to wear numbers 90 to 99.
- The penalty for a kickoff or onside kick that goes out of bounds is 5 yards from the previous spot and a re-kick must be made. However, if the second (or more) kickoff or onside kick goes out of bounds, the receiving team may choose instead to take possession of the ball at the out of bounds spot.
- Leaping to try to block a field goal or an extra point is illegal unless the defensive player was lined up at the line of scrimmage.
- A kicker or holder who fakes being roughed or run into by a defensive player can receive an unsportsmanlike conduct penalty.
- Unsportsmanlike conduct will also be called for any prolonged, excessive, or premeditated celebration by individual players or a group of players. This is usually referred to as the “Mark Gastineau Rule” because a major reason why this change was made was to stop him from performing his signature “Sack Dance” every time after he sacked an opposing quarterback. This also referred to the Washington Redskins "Fun Bunch".
