The ATP Finals is the second highest tier of annual men's tennis tournament after the four Grand Slam tournaments.
A week-long event, the tournament is held annually each November at the O2 Arena in London, United Kingdom. The ATP Finals are the season-ending championships of the ATP Tour and feature the top eight singles players and doubles teams of the ATP Rankings. The tournament was first held in 1970, although it was known under a different name.
In the current tournament, winners are awarded up to 1500 ranking points; with each round-robin loss, 200 points are deducted from that amount.
The event is the fourth evolution of a championship which began in 1970. It was originally known as the Masters Grand Prix and was part of the Grand Prix Tennis Circuit. It was organised by the International Lawn Tennis Federation (ILTF). It ran alongside the competing WCT Finals the season-ending championships for the rival World Championship Tennis Tour. The Masters was a year-end showpiece event between the best players on the men's tour, but did not count for any world ranking points.
In 1990, the Association of Tennis Professionals (ATP) took over the running of the men's tour and replaced the Masters with the ATP Tour World Championship. World ranking points were now at stake, with an undefeated champion earning the same number of points they would for winning one of the four Grand Slam events. The ITF, who continued to run the Grand Slam tournaments, created a rival year-end event known as the Grand Slam Cup, which was contested by the 16 players with the best records in Grand Slam competitions that year.
In December 1999, the ATP and ITF agreed to discontinue the two separate events and create a new jointly-owned event called the Tennis Masters Cup. As with the Masters Grand Prix and the ATP Tour World Championships, the Tennis Masters Cup was contested by eight players. However, player who is ranked number eight in the ATP Champion's Race world rankings does not have a guaranteed spot. If a player who wins one of the year's Grand Slam events finishes the year ranked outside the top eight but still within the top 20, he is included in the Tennis Masters Cup instead of the eighth-ranked player. If two players outside the top eight win Grand Slam events, the higher placed player in the world rankings takes the final spot in the Tennis Masters Cup.
In 2009, the Masters was renamed the ATP World Tour Finals and was held at The O2 in London from 2009 to 2013. In 2012, the organisers extended the contract by two years up to 2015.In 2015, the contract was extended again for three years up to 2018. In 2017 the event was renamed the ATP Finals and the contract with the O2 Arena was extended to 2020. In December 2018 it was announced that London, along with Manchester, Singapore, Tokyo and Turin were on a shortlist of five cities which made the cut from an initial list of 40 to host the event from 2021.
For many years, the doubles event was held as a separate tournament the week after the singles competition, but more recently they have been held together in the same week and venue.
For most of its history, the event has been considered as the most important indoor tennis tournament on the world tour (there were a few exceptions, when the event was organized outdoors: 1974 Melbourne & 2003–2004 Houston), allowing for controlled conditions of play, regarding both surface type and illumination system.
In recent years it has been played on indoor hard courts, however, indoor carpet has featured for many editions previously. Once when Melbourne hosted it in 1974 the grass courts of Kooyong Stadium were used  and occurred a few weeks before the 1974 Australian Open, which were also played on grass. Apart from 1974, all tournaments have been on a hard court variant, which has prompted calls, primarily from Rafael Nadal    to feature a mix of surfaces and include clay courts. However, this has drawn criticism  as well as suggestions to reduce the number of clay court tournaments in the season  and the ATP are not keen to change this aspect of the tournament. 
There are eight players or teams, and playing is mandatory except for injury or other good cause.
Qualification is as follows:
(a) the top seven players in the ATP rankings (b) up to two grand slam winners ranked between 8 and 20 (in order of ATP ranking, if any such players exist) (c) the next players in the ATP rankings, until the quota of eight is reached.
Points, prize money and trophies
The ATP Finals currently (2018) rewards the following points and prize money, per victory:
|Round Robin (each of 3 matches)||$213,000||$38,000||200|
- 1 Prize money for doubles is per team.
There is also an appearance fee of $203,000 singles, and $100,000 per doubles team. The two alternates are paid $110,000 (singles) and $38,000 (doubles teams).
An undefeated champion would earn the maximum 1,500 points, and $2,712,000 in singles or $517,000 in doubles.
Unlike all other singles events on the men's tour, the ATP Finals is not a straightforward knock-out tournament. Eight players are divided into two groups of four and play three round-robin matches each against the other players in their group. The two players with the best records in each group progress to the semifinals, with the winners meeting in the final to determine the champion. Though it is theoretically possible to advance to the semi-finals of the tournament with two round-robin losses no player in the history of the singles tournament has won the title after losing more than one round-robin match.
The current round robin format of two groups of four players progressing to a semifinal and final, has been in place for all editions of the tournament except the following years:
- 1970, 1971 – Round robin with no semifinals or finals, winner decided on best performed player
- 1982, 1983, 1984 – 12 player knock-out tournament with no round robin. The top four seeds in the event received a bye in the first round.
- 1985 – 16 player knock-out tournament with no round robin
The tournament has traditionally been sponsored by the title sponsor of the tour; however, from 1990–2008 the competition was non-sponsored, even though the singles portion of the event as part of the ATP tour was sponsored by IBM. In 2009, the tournament gained Barclays PLC as title sponsor. Barclays confirmed in 2015 that they would not renew their sponsorship deal once it expires in 2016.
