The 1965NFL playoffs determined the champion of the National Football League in professional American football. Although a single championship game between conference winners was the current format for the league, a tie in the Western Conference standings between the Green Bay Packers and Baltimore Colts necessitated a divisional playoff game. Although the championship game was played in 1966, it is recognized as part of the 1965 NFL season. The 1965 Championship Game was the latest date for an NFL Championship Game to that point, and the first time in league history that the game was held after all of the college bowl games.
The Playoff Bowl (a consolation game between the second place team from each conference) for the 1965 season took place on January 9, 1966. The Colts defeated the Dallas Cowboys 35–3. This capped a season where the Western Conference won 15 out of 16 interconference games against the Eastern Conference, including the championship game and Playoff Bowl.
