The 1949 NFL season was the 30th regular season of the National Football League. Prior to the season, Boston Yanks owner Ted Collins asked the league to fold his team due to financial woes, and give him a new one in New York City. This new team would be called the New York Bulldogs. As a result, professional football would not return to Boston until the Patriots began play in 1960.
As the regular season came to a close, a merger agreement between the NFL and the All-America Football Conference was announced on December 9. Three AAFC teams joined the NFL in 1950, the Cleveland Browns, San Francisco 49ers, and Baltimore Colts.  
The season ended on December 18 with the NFL Championship Game. In muddy conditions, the visiting Philadelphia Eagles defeated the Los Angeles Rams 14–0, as heavy rain in southern California kept the attendance under 23,000 at the Los Angeles Memorial Coliseum.  Both teams had potent offenses, but were severely limited by the poor field conditions. The management of the Eagles and Rams had favored a postponement for a week, but were overruled by commissioner Bert Bell. 
- The free substitution rule (any or all of the players may be replaced by substitutes after any play) was re-adopted for one year. The rule was previously adopted in 1943 in response to the depleted rosters during World War II, but repealed in 1946.
- Plastic helmets allowed again, after being outlawed in 1948.
In the Eastern Division, Philadelphia and Pittsburgh both had records of 4–1–0 when they met in Week Six. The Eagles won 38–7, and kept the lead for the remainder of the season. In the Western Division, the Rams got off to a 6–0–0 start while the Bears were 3–3–0 at midseason. Though the Bears won all of their remaining games, they never caught up to the Rams, who finished at 8–2–2.
Had the current (post-1972) system of counting ties as half a win and half a loss been in place in 1949, the Rams would have required a playoff with the Bears for the Western Division.
W = Wins, L = Losses, T = Ties, PCT= Winning Percentage, PF= Points For, PA = Points Against
Note: The NFL did not officially count tie games in the standings until 1972
