1980–81 Philadelphia Flyers season

The 1980–81 Philadelphia Flyers season was the Flyers' 14th season in the National Hockey League (NHL). After finishing second in the Patrick Division, the Flyers lost in the quarterfinals to the Calgary Flames in seven games.

Regular season
Bobby Clarke wore the number 16 throughout his entire NHL career except for two games during the 1980–81 season. Prior to a road game on February 27, 1981, Clarke's jersey was stolen. Clarke wore the only other jersey available, number 36, in the next two games. A month later, Clarke hit a personal milestone in memorable fashion. On March 19 during a game against the Boston Bruins, a Reggie Leach slapshot struck Clarke. After leaving the ice, he re-appeared moments later stitched up and with his jersey covered in blood. 31 seconds into the third period Clarke beat Bruins goalie Marco Baron for his 19th goal of the season and his 1,000th career point.

Playoffs
After a tough, five-game preliminary round series win against the Quebec Nordiques, the Flyers moved on to face the Calgary Flames in the quarterfinals. After falling behind 3 games to 1, they managed to force a Game 7 by winning the next two games. The Flyers lost Game 7, 4–1, at the Spectrum.
