In a game of tennis, the slang term 'bagel' refers to a set that ends with a score of six games to love. This means one player won six games and the other did not win any. It is called a 'bagel' because the zero in the score of 6-0 resembles the shape of a bagel. A 'double bagel' may occur when the score is 6-0, 6-0 after two sets have been played. Similarly, a 'triple bagel' is when the score of a match is 6-0, 6-0, 6-0.

In 2004, the Association of Tennis Professionals began awarding the players who won the most 'bagels' during a single season with a 'golden bagel' award. The first winner was Roger Federer with 12 'bagels'. Other winners include Rafael Nadal, who holds the record of 18 'bagels', David Ferre, Robin Söderling and Novak Djokovic.

As of 2022, the player with the most 'bagels' in their entire career is Jimmy Connors with 180. Ivan Lendl is currently in second place with 148. Since 1968, there have only been six instances of a 'triple bagel' during a Grand Slam game. These were won by Nikola Špear (1968), Karel Nováček (1987), Stefan Edberg (1987), Ivan Lendl (1978), Sergi Bruguera (1993) and Todd Woodbridge (2001).
