The 1980 Oakland Raiders season began with the team trying to improve on their 9–7 record from 1979. It was the 20th anniversary of the Oakland Raiders franchise and ended with their second Super Bowl victory. Prior to the start of the season Al Davis announced plans to move the Raiders from Oakland to Los Angeles. However, NFL Commissioner Pete Rozelle blocked the move by filing a restraining order. He would even try to get Al Davis removed as owner, as the case went to the courts. Still playing in Oakland the Raiders entered the season with a new Quarterback after acquiring Dan Pastorini from the Houston Oilers for Kenny Stabler. However Pastorini struggled and the Raiders got off to a 2-3 when Pastorini was injured and replaced by Jim Plunkett. Plunkett proved right for the Raiders offense as the team played solid football the rest of the season compiling an 11-5 record, and qualifying for the playoffs as a Wild Card. In the Wild Card Game the Raiders would beat the Houston Oilers 27-7 at Oakland as the Raiders defense picked former teammate Kenny Stabler off twice. Playing in freezing weather with temperature reading 30 degrees below zero the Raiders stunned the Browns 14-12 in a defensive struggle in Cleveland. In the AFC Championship Game in San Diego the game would be a shoot out as the Raiders stunned the Chargers 34-27 to become the first AFC Wild Card to make the Super Bowl.

Five weeks into the Raiders season, starting QB Dan Pastorini broke his leg in a game against the Kansas City Chiefs. 32-year-old Jim Plunkett came off the bench to relieve Pastorini and had a terrible performance, throwing 5 interceptions in a 31–17 loss. The Raiders, thinking that Marc Wilson did not have the experience they wanted, called on Plunkett to start for the remainder of the year. In his first game as a starter, he completed eleven of fourteen passes with a touchdown and no interceptions, beginning one of the greatest comeback stories in the history of the sport. Plunkett guided Oakland to nine victories in eleven games and a playoff berth as a wild-card. Then, even more remarkably, rather than suffering an early defeat which marks the typical fate of NFL wild card teams, Plunkett led the Raiders to four playoff victories, including the Super Bowl, where they defeated the Philadelphia Eagles, 27–10, in Super Bowl XV. Throwing for 261 yards and three touchdowns, Plunkett was named the game's MVP.
At wide receiver, Cliff Branch re-emerged again as one of the games deep threats and had his best season since 1977. Bob Chandler, the other WR, had one of his best seasons, leading the team in receptions (49) and TDs (10).
All – Pro veteran Raymond Chester at tight end also contributed with timely big plays throughout the year and in the post season. On defense, the Raiders were led by Lester Hayes who arguably had the best season for a cornerback in NFL history – 18 interceptions, 2 TDs in 19 games played. Oakland led the NFL in interceptions (35) and takeaways (52) and 2nd in sacks with 54. Hayes was known for using "stickum" and would have stickum all over his upper body. After the season, the NFL prohibited its use.
The Raiders' Super Bowl win was the first by an NFL wild card team and the second by a non-division champion. The Kansas City Chiefs won Super Bowl IV after finishing second to the Raiders in the AFL West Division during the 1969 season.
The Raiders clinched a wild card spot and a home playoff game with the win over the Giants. Oakland was now 9–2 since Jim Plunkett had taken over as the team's starting quarterback. "I'm not really amazed", Plunkett said. "I felt that this team had a chance to make it into the playoffs. I'm just thankful I had these opportunities to play. I just kept plugging away and I think it turned out OK."
Three plays into the Giants' next drive, Gary Shirk caught a Scott Brunner pass but fumbled it away. Luckily, the Raiders couldn't capitalize as Bahr's 52-yard field goal attempt was short.
A Joe Danelo field goal put New York on the scoreboard but Plunkett completed passes of 12 and 11 yards to Bob Chandler before finding Cliff Branch caught a pass between Eric Felton and Steve Henry at the Giants' 10 and strode in to give Oakland a 17–3 lead with 6:29 left in the first half. Three plays following the kickoff, Lester Hayes picked off Brunner and returned it 50 yards to the New York 19. The Raiders failed to move and Bahr kicked a 38-yard field goal to increase the lead to 20–3 with 2:55 left.
New York scored their first touchdown on a touchdown pass from Scott Brunner to Leon Perry before halftime but Oakland took control on a 37-yard bomb from Plunkett to Raymond Chester late in the third quarter. Billy Taylor scored in the closing seconds following a pass interference penalty by Hayes in the end zone but an onside kick attempt by Joe Danelo went right to Derrick Jensen, who sprinted into the end zone.
