Several tiebreaks have been attributed as the longest tiebreak in tennis.
Match tie-breaks (also referred to as supertiebreakers or champions tie-breaks), where a single game is used to decide a match when the score is one set all, have been in general use in doubles matches on the professional tours since the early 2000s. Although it had previously been used occasionally in tournaments affected by bad weather, from the beginning of 2019 the "10 point" match tie-break also became the official method of deciding singles qualifying matches which had reached one set all in ITF tournaments. From the beginning of 2023, when $40,000 tournaments were added to the ITF women's calendar, this rule was changed to apply only to $15,000 and $25,000 tournaments, with all higher-ranked events reverting to the best of three tie-break sets.
In 2022 a rule change was agreed to by every Grand Slam tournament, as well as the Olympic Games from 2024, that a 10-point (rather than 7 point) tie-break would be played once the deciding set became tied at 6 games all.
The tennis scoring system is a standard widespread method for scoring tennis matches, including pick-up games. Some tennis matches are played as part of a tournament, which may have various categories, such as singles and doubles. The great majority are organised as a single-elimination tournament, with competitors being eliminated after a single loss, and the overall winner being the last competitor without a loss. Optimally, such tournaments have a number of competitors equal to a power of two in order to fully fill out a single elimination bracket. In many professional and top-level amateur events, the brackets are seeded according to a recognised ranking system, in order to keep the best players in the field from facing each other until as late in the tournament as possible; additionally, if byes are necessary because of a less-than-full bracket, those byes in the first round are usually given to the highest-seeded competitors.

This article details longest tennis match records by duration or number of games. The 1970–1973 introduction of the tiebreak reduced the opportunity for such records to be broken. However, among the four majors, the US Open, Australian Open and Wimbledon use the tiebreak in the final set, while the French Open, through 2021, was the only major to use the advantage set rules in the final set, which allows for an indefinite number of games until one player is ahead by two. A 2022 rule change now requires every Grand Slam tournament, even the Olympics, to use the tiebreak in the final set.
