The 1988Philadelphia Eagles season resulted in a winning season and an appearance in the postseason for the first time since 1981. The Eagles won the NFC East for the first time in seven seasons, but lost to the Chicago Bears in the NFC Divisional round during the Fog Bowl.
On the final day of the regular season, Philadelphia dumped Dallas, 23–7, but had to wait for the end to the Jets-Giants game at Giants Stadium to learn if they had clinched the division or not. The Jets won the game, 27–21, on a late TD strike from Ken O'Brien to Al Toon, giving the Eagles the NFC East crown on the tiebreaker of having beaten the Giants in both regular-season meetings.
Known as The Fog Bowl, the Bears defeated the Eagles, 20–12, in a contest in which a heavy, dense fog rolled over Chicago's Soldier Field during the second quarter and cut visibility to about 15–20 yards for the rest of the game.
