Due to Christmas, the Divisional playoff games were held in a span of three days. The AFC playoff games were played on Saturday December 24 while the NFC games were held on Monday December 26. It also marked the only year since the AFL–NFL merger in 1970 that one conference held both of its divisional playoff games on one day and the other conference held both of its games on the other day. In every other season since 1970, the conferences have split their playoff games over the two days.

This was also the last season that the NFL used an eight-team playoff tournament.

Within each conference, the three division winners and one wild card team (the top non-division winner with the best overall regular season records) qualified for the playoffs. The three division winners were seeded 1 through 3 based on their overall won-lost-tied record, and the wild card team was seeded 4. The first round, the divisional playoffs, had a restriction where two teams from the same division could not meet: the surviving wild card team visited the division champion outside its own division that had the higher seed, and the remaining two teams from that conference played each other. The two surviving teams from each conference's divisional playoff games then meet in the respective AFC and NFC Conference Championship games, hosted by the higher seed. Although the Super Bowl, the third and final round of the playoffs, was played at a neutral site, the designated home team was based on an annual rotation by conference.

On a play known as the "Ghost to the Post", Raiders quarterback Ken Stabler threw a 42-yard completion to tight end Dave Casper on a post route to set up the game-tying field goal with 29 seconds left in regulation. Casper, nicknamed "The Ghost" by his teammates, also caught a 10-yard touchdown pass 43 seconds into the second overtime period to win the game. The game featured nine lead changes before it was over.
