No. The 1972 Miami Dolphins are the only team to finish the season undefeated (17-0).
The last men's team to go undefeated during the regular season and win the tournament was Indiana in 1976.
Miami dolphins
The 72' Miami Dolphins went undefeated in a 14 game regular season and then went on to win the Superbowl. The 85' Chicago Bears were in line for an undefeated season and suffered their only loss to.... the Miami Dolphins! The 2007 New England Patriots went undefeated during the regular season, the only team to do so with a 16 game schedule, and would eventually lose to the New York Giants in the Superbowl.
The Miami Dolphins went undefeated in 1972. They are still the only team to go undefeated during the regular season to go on and win the Super Bowl.

There has never been a Major League baseball team to go undefeated in a season.

Yes, the Dolphins in 1972 went undefeated during the regular season and won the Super Bowl. The 1934 and 1942 Chicago Bears went undefeated during the regular season but lost the NFL championship game both seasons. The Patriots just finished the 2007 regular season undefeated. The question was "Was there ever and undefeated NFL Season?" If you're referring to a regular season AND championship win...there was only one...the 1972 Miami Dolphins. If you're referring to and undefeated regular season only...four teams have done this...they are: 1943 Chicago Bears 1942 Chicago Bears 1972 Miami Dolphins 2007 New England Patriots Both of the above answers are inaccurate. The first team to go undefeated through an ENTIRE NFL SEASON and win the CHAMPIONSHIP was the Green Bay Packers in 1929. Curly Lambeau was their coach. The Dolphins were the 2nd team to do it, 43 years later, without resorting to any ties (NFL had tie games in those days and the Packers had 1 tie). The Packers and Dolphins are the ONLY teams to ever accomplish an undefeated NFL Championship.
