List of last undefeated NFL teams by season

This is a season-by-season breakdown of the last undefeated National Football League (NFL) team (or teams) in each league, including playoffs. This list indicates the teams who won the most games in a season before suffering their first loss.[1]

The 1920 Akron Pros compiled an undefeated record in the NFL's inaugural season.
Jim Kiick rushing the ball for Miami in Super Bowl VII. The win capped a perfect season for the 1972 team.
After 40 years, President Obama honored the 1972 Dolphins at the White House in 2013.
Curly Lambeau was coach for the unbeaten 1929 Packers.
The 2006 Colts, at the White House with President Bush, are the most recent team to be the last undefeated team remaining to win the Super Bowl.

The last team in a new season to suffer a loss has won the Super Bowl twelve times. Before the Super Bowl era, the last undefeated team won fourteen Championship games, four of which were in the AFL. The last team with an unblemished record has made 25 Super Bowl and 26 Championship game appearances.

The Bears have been the last team undefeated 17 times (the last time was during the 2010 season), while the next team, the Rams, have been the last team beaten 12 times as of the 2018 season. The Giants hold the mark for beating the last undefeated team. They have accomplished this 11 times; the last time it happened was in 2010.
