The National Football League playoffs for the 1975 season began on December 27, 1975. The postseason tournament concluded with the Pittsburgh Steelers defeating the Dallas Cowboys in Super Bowl X, 2117, on January 18, 1976, at the Orange Bowl in Miami, Florida.
This was the first season in which the league used a seeding system in the playoffs. Thus, the surviving clubs with the higher seeds were made the home teams for each playoff round. The three division champions in each conference were seeded 1 through 3 based on their regular season won-lost-tied record, and the wild card qualifier in each conference became the 4 seed.
However, the league continued to prohibit meetings between two teams from the same division in the Divisional Playoffs. Thus, there would be times when the pairing in that round would be the 1 seed vs. the 3 seed and 2 vs. 4.
