This list shows the appearances of all participants in the men's tennis ATP Finals singles since their inception as the Pepsi-Cola Masters in 1970. The tournament is currently held in Pala Alpitour in Turin, Italy.
Qualification
editThe criteria to qualify for the ATP Finals are as follows:
- Players and teams who finish the season ranked in the top seven in the ATP race automatically qualify.
- The eighth spot is reserved for a player or team who won a major in the season and is ranked from eighth to twentieth. Goran Ivanišević in 2001, Albert Costa in 2002, Gastón Gaudio in 2004, and Marin Čilić in 2014 are the singles players who have qualified due to their major title despite not ending in the top eight in the ATP race.
- If more than one player or team won a Grand Slam event in the season and are ranked from eighth to twentieth, then whoever is highest-ranked is awarded the eighth spot; whoever is second highest-ranked is made first alternate.
- If there is no player who won a major in the season and is ranked from eighth to twentieth, then the eight spot is awarded to the player ranked eighth.
Two alternates also attend the ATP Finals. If the first alternate has already been selected according to (3) mentioned above, then the second alternate is the highest-ranked player who has not otherwise qualified for the event. If both alternate spots are available, they are awarded to the two highest-ranked players who did not otherwise qualify for the event.
An alternate can replace a player who withdraws before the round-robin stage is over, so long as the player who withdraws still has at least one round-robin match left to play. When an alternate enters the competition, his results are considered separately, i.e. the alternate does not inherit the results of the player he is replacing. If an alternate's round-robin results qualify him for the semifinals, then he may continue into the single-elimination rounds.
Format
editUnlike other events on the ATP Tour, the ATP Finals is not a straightforward single-elimination tournament. The eight players and teams are divided into two groups of four and each play three round-robin matches against the others in their group. After the round-robin stage, the top two performers in each group advance to the semifinals in a knock-out stage. The two winners of the semifinals play a final to determine the champion. In this format, it is theoretically possible to advance to the semifinals with two round-robin losses, but no player in the history of the singles tournament has won the title after losing more than one round-robin match.
To create the groups, the eight players and teams are seeded according to rank. The first and second seeds are placed in Group A and Group B, respectively. The remaining seeds are drawn in pairs (third and fourth, fifth and sixth, seventh and eighth); the first of the pair to be drawn goes to Group A and the other to Group B, and so on.
The format described above has been in place for all editions of the tournament except the following years:
- 1970–71: All round robin (no groups), no semifinals or finals, the winner was decided based on round-robin standings.
- 1982–84: 12-player three-round single-elimination tournament (no round robin), the top four seeds received byes in the first round.
- 1985: 16-player four-round single-elimination tournament (no round robin), no byes.

- Note
When there are more than eight players listed for any year since 1986, it is usually due to withdrawal by one or more players because of injury. When a player withdraws early in the tournament, his place is filled by the next-highest qualifier.
Participants are listed in order of (1) number of appearances, (2) best result(s) (bolded years for wins, underlined years for other best results), (3) year of first appearance, and (4) alphabetical order if still tied. Active players are indicated in bold.
