The National Football League playoffs for the 1985 season began on December 28, 1985. The postseason tournament concluded with the Chicago Bears defeating the New England Patriots in Super Bowl XX, 46–10, on January 26, 1986, at the Louisiana Superdome in New Orleans, Louisiana.

Within each conference, the three division winners and the two non-division winners with the best overall regular season records qualified for the playoffs. The NFL did not use a fixed-bracket playoff system. The three division winners were seeded 1–3 based on their overall won-lost-tied record, and received a first-round bye while the wild card teams were seeded 4 and 5, and played in the first round, dubbed the wild-card playoffs or wild-card weekend, with the 4 seed hosting. The second 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 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 met in the respective AFC and NFC Conference Championship games, hosted by the higher seed. Finally the Super Bowl, the championship round of the playoffs, was played at a neutral site, with the designated home team based on an annual rotation by conference.

Because the Jets and Giants both used Giants Stadium as their home field, the two wild card playoff games were held on different days.

In the United States, CBS televised the NFC playoff games, while NBC broadcast the AFC games and Super Bowl XX.

This was the first postseason meeting between the Patriots and Jets. In the NFL's first playoff game at Giants Stadium, the Patriots dominated the game by forcing five sacks and four turnovers from a Jets offense that had ranked #1 during the season for fewest turnovers lost (29). This was New England's first playoff win since 1963.

New England jumped to 3–0 lead in the first quarter after Tony Franklin made a 33-yard field goal. Then after New York scored on quarterback Ken O'Brien's 11-yard touchdown pass to running back Johnny Hector, Franklin kicked his second field goal from 41 yards. Late in the second quarter, safety Fred Marion intercepted a pass from O'Brien and returned it 26 yards to the Jets 33-yard line. A few plays later, Jets defensive back Russell Carter failed to make contact with receiver Stanley Morgan while trying to jam him at the line of scrimmage, enabling Morgan to take off past Carter and haul in a 36-yard touchdown completion from Tony Eason, giving New England a 13–7 halftime lead.

In the third quarter, Franklin made a 20-yard field goal to give the Patriots a 16–7 lead and on the ensuing kickoff, Hector was stripped of the ball by linebacker Johnny Rembert, who then picked up the fumble and returned it 15 yards for a touchdown, which gave the Patriots a commanding 23–7 lead. However, Hector returned the next kickoff 33 yards to the Pats 43-yard line. From there, Pat Ryan replaced O'Brien, who had been suffering from a concussion since the first half, and completed 5/7 passes on a 57-yard scoring drive, the last a 12-yard touchdown throw to tight end Mickey Shuler, making the score 23–14. But in the fourth quarter, Patriots linebacker Andre Tippett deflected a Ryan pass into the arms of defensive end Garin Veris, who returned the interception 18 yards to set up Franklin's fourth field goal and finish off the scoring.
