The 2020 season was the Tampa Bay Buccaneers' 45th in the National Football League and their second under head coach Bruce Arians. The club improved on their 7–9 record from the previous season by finishing 11–5 to qualify for the playoffs for the first time since 2007. They advanced through the playoffs to reach and win Super Bowl LV. They were the first wild card team and first team only having one Pro Bowler to do so since the 2010 Packers and 2007 Giants respectively, and the first team to play in and win the Super Bowl in their home stadium, Raymond James Stadium. They were the 7th wild card team in NFL history to win the Super Bowl as well as the 5th team to win three road games to advance to the Super Bowl, joining the 2010 Packers, 2007 Giants, 2005 Pittsburgh Steelers, and 1985 New England Patriots.
The team unveiled new uniforms in April 2020, their first uniform change since 2014. The uniforms are similar in design to the ones they wore from 1997 to 2013.
Super Bowl LV was the championship game of the National Football League (NFL) for the 2020 NFL season. The National Football Conference (NFC) champion Tampa Bay Buccaneers defeated the American Football Conference (AFC) champion Kansas City Chiefs, 31–9. The game took place on February 7, 2021, at Raymond James Stadium in Tampa, Florida, the home stadium of the Buccaneers, marking the first time that a team played a Super Bowl in its home stadium. Due to COVID-19 protocols limiting the stadium's seating capacity to 25,000 fans, it was the least-attended Super Bowl.
The Buccaneers' victory was their second and made them the only team other than the Baltimore Ravens to be undefeated in multiple Super Bowls. They finished the regular season with an 11–5 record and a wild card berth to advance to their second Super Bowl appearance through the guidance of several new acquisitions, most notably veteran quarterback Tom Brady in his first season away from the New England Patriots, who was the Super Bowl's oldest player at 43. The Chiefs, aided by their top-ranked offense, finished the regular season with a league-best 14–2 record to advance to their fourth Super Bowl appearance and were the defending Super Bowl LIV champions, seeking to become the first repeat champions since the Patriots in 2004.
Kansas City entered the game favored to win, but were undone by offensive struggles and costly penalties. For the first time under quarterback Patrick Mahomes, the Chiefs failed to score a touchdown and lost by double-digits, making them the third Super Bowl team to not score a touchdown.They committed 11 penalties for 120 yards, including a record eight penalties for 95 yards in the first half, most of which were called against the defense.The Buccaneers capitalized on these mistakes to take a commanding 21–6 lead at halftime and dominated the remainder of the game. Brady, who also extended his player records for Super Bowl appearances at 10 and wins at seven, was named Super Bowl MVP for a record fifth time and was the first to receive the award with multiple franchises. He became the oldest player to receive the honor and win a Super Bowl as the starting quarterback, breaking additional personal records, while Bruce Arians was the oldest head coach to win the Super Bowl at 68.
The game was televised nationally by CBS. Country music singer Eric Church and R&B singer Jazmine Sullivan performed the national anthem, while the halftime show was headlined by Canadian singer The Weeknd. On television, Super Bowl LV was seen by 91.63 million viewers, the lowest ratings for the game since 2006. Combined with viewership on other platforms, viewership was down by 5% overall in comparison to Super Bowl LIV, but with a 69% increase in average streaming viewership.
