The 1985 New York Giants season was the 61st season for the club in the National Football League (NFL).
 The Giants entered the season looking to improve on their 9–7 record in 1984, which was enough to qualify the team for the playoffs as the second wild-card team, and to return to the playoffs for the second consecutive year under third-year head coach Bill Parcells.
 The Giants managed to do both, finishing with 10 victories for the first time since 1963 when the team won 11 games and finishing as the first wild-card team which earned the Giants a home playoff game at Giants Stadium.
 They defeated the San Francisco 49ers 17–3 in that game, avenging their loss to the 49ers in the previous year's divisional playoffs.
 However, it was as far as the Giants could get as they were defeated by the eventual Super Bowl champion Chicago Bears in the divisional round at Soldier Field 21–0.
 Bill Parcells stated in "America's Game: 1986 Giants" that the game the Giants played against the Bears in the playoffs that "an honest evaluation of it, we could have probably beat that team one out of ten times.
 But that day was one of the days that that could have happened", the Giants were ultimately undone by a whiffed punt from legend Sean Landeta, the ball flew out of the air when he went to punt it from a burst of wind coming of Lake Michigan, the Bears recovered the ball for a touchdown from less than 5 yards from the end zone, and ended up winning 21-0.
 At the time, the team set a record for most rushing yards in one season by a Giants team.
