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 (since 2019) 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 to use the tiebreak in the final set. The Olympic Games have also used a final set tiebreak since 2016.
