ATP stands for Association of Tennis Professionals. It is the organization behind the leading worldwide tour for men’s professional tennis, including the ATP Tour, the ATP Challenger Tour and the PIF ATP Rankings.
The acronym can also appear before tournament categories, ranking positions and statistics. It does not mean that the ATP runs every men’s tennis competition. The four Grand Slam tournaments, the ITF’s World Tennis Tour, the Davis Cup and Olympic tennis have different organizers and governance arrangements.

What Does the Association of Tennis Professionals Do?
The ATP organizes and governs much of the top level of men’s professional tennis. Its work includes maintaining tour calendars and tournament standards, administering player entry systems, publishing rankings, supporting on-site operations and presenting the sport to fans and commercial partners.
Its two main competitive circuits serve different levels of the professional pathway:
- The ATP Tour is the leading men’s circuit and includes ATP 250, ATP 500 and ATP Masters 1000 tournaments, plus the season-ending ATP Finals and Next Gen ATP Finals.
- The ATP Challenger Tour sits below the ATP Tour and gives professionals opportunities to compete for ranking points and progress toward higher-level events.
Tournament categories, draw sizes and entry routes are explained more fully in Types of Tennis Tournaments and How They Work.
Why Was the ATP Created?
The ATP was formed in September 1972, when a group of leading players met during the US Open at Forest Hills in New York. The aim was to give professional players a collective voice in decisions affecting their careers and the sport.
Cliff Drysdale became the organization’s first president, and Jack Kramer served as its first executive director. In 1973, the ATP introduced a computer-based men’s ranking system intended to replace inconsistent and subjective methods of determining tournament entry.
The modern ATP Tour began in 1990. That development gave players and tournaments a shared structure for the leading men’s circuit rather than leaving the schedule under a collection of separate arrangements.
How Is the ATP Governed?
The ATP describes itself as an equal partnership between players and tournaments. Both groups have representation in its governance, with a chairman leading a board that includes player and tournament representatives.
Player and tournament advisory bodies provide input from their respective groups. This structure is important because the interests of a touring player, a tournament organizer and the tour as a whole can overlap without always being identical.
The ATP also employs teams that work in areas such as tournament relations, player relations, medical services, communications, technology, legal affairs and tour development.

ATP Tour Tournament Levels
The principal ATP Tour levels indicate a tournament’s position within the men’s circuit.
| Level | General role in the tour |
|---|---|
| ATP Masters 1000 | Highest regular ATP Tour category below the majors and ATP Finals |
| ATP 500 | Major tour events below Masters 1000 level |
| ATP 250 | Broadest regular ATP Tour category and an important entry point to tour-level competition |
| ATP Finals | Season-ending event for the leading qualified singles players and doubles teams |
| Next Gen ATP Finals | Season-ending event for leading qualified young players under its current eligibility rules |
| ATP Challenger Tour | Developmental professional circuit below the ATP Tour |
The numbers in the regular tour categories relate to the maximum singles ranking points awarded to the champion. They do not represent prize money, draw size or the number of tournaments in the category.
The ATP Finals has its own qualification and points structure, while Grand Slam tournaments sit outside the ATP 250, 500 and Masters 1000 ladder.
What Are the ATP Rankings?
The ATP publishes separate rankings for men’s singles and doubles. Those rankings are used for purposes such as tournament entry, seeding and qualification, subject to the rules of each event.
Players earn points from eligible results across a defined ranking period. The detailed calculation includes event categories, countable results and participation rules, so it is better treated as its own subject. What Is the Tennis World Ranking? explains the ranking mechanics without confusing them with the ATP’s wider organizational role.
An ATP ranking is not the same as a player’s seed at a particular tournament. A seed is a position assigned within one draw, usually using rankings under that event’s rules, while a ranking is the player’s position on the published list.
ATP Tour vs ATP Challenger Tour
Both circuits are administered within the ATP system, but they occupy different competitive levels.
| ATP Tour | ATP Challenger Tour |
|---|---|
| Features the leading regular men’s events | Provides the next tier of professional competition |
| Includes 250, 500 and Masters 1000 categories | Uses Challenger categories under the current calendar |
| Generally offers more ranking points and prize money | Generally offers fewer points and lower prize money than comparable tour-level events |
| Harder to enter directly without a high ranking or another entry route | A common pathway for players building or rebuilding a ranking |
The Challenger Tour is not an amateur circuit. Its entrants are professional players, and fields can include emerging prospects, established specialists and experienced tour players returning from injury or seeking ranking points.
ATP vs ITF, WTA and the Grand Slams
Professional tennis is not controlled by one organization. The main bodies have related but distinct responsibilities.
| Organization or event group | Main role |
|---|---|
| ATP | Leading men’s professional tour, Challenger Tour and men’s professional rankings |
| WTA | Leading women’s professional tour and women’s professional rankings |
| ITF | International governing body responsible for the Rules of Tennis and a range of world tours and team competitions |
| Grand Slam tournaments | Four independently organized majors operating under the Grand Slam governance structure |
The Australian Open, Roland Garros, Wimbledon and the US Open appear prominently on the professional calendar and award ATP and WTA ranking points, but they are not ATP or WTA tournaments. The ITF is responsible for the Rules of Tennis, while individual competitions can also have event-specific regulations consistent with that framework.
This division explains why a tournament may appear on the ATP calendar without being owned or operated by the ATP.
What Does ATP Mean Beside a Player’s Name?
When ATP appears beside a number, it usually refers to the player’s position in the men’s rankings. For example, “ATP No.” followed by a number identifies that player’s place on the relevant ATP list at that time.
Rankings change as new results are added and older results cease to count. A number quoted without a date can therefore become misleading, especially for active players.
ATP may also appear before a tournament category, such as ATP 500, or as part of a branded statistic. The surrounding context shows whether the acronym refers to the organization, a tour level or its ranking system.
How Does a Player Reach the ATP Tour?
There is no single application that turns a player into an ATP Tour competitor. Players normally build results and ranking points through eligible professional events, then use their ranking or another valid entry route to enter stronger tournaments.
The pathway can include ITF men’s events, ATP Challengers and eventually ATP Tour qualifying or main draws. Wild cards, qualifying places, special-exempt provisions and other entry routes are governed by tournament and tour rules rather than by reputation alone.
The practical development path involves a much wider combination of playing level, results, travel, coaching and finances. How to Become a Professional Tennis Player covers those demands in more detail, while How Do Tennis Players Make Money? explains why being professionally ranked does not automatically make a career profitable.
Common Misunderstandings About the ATP
ATP Does Not Mean Every Men’s Tennis Event
The ATP is central to men’s professional tennis, but the ITF, Grand Slam organizations, national associations and event owners also have defined roles. Junior, college, amateur and many national competitions do not sit within the ATP Tour.
ATP and WTA Are Not Ranking Categories
They are separate professional tour organizations. Each publishes its own rankings for its respective tour rather than placing all players on one combined list.
ATP 500 Does Not Describe Prize Money
The number identifies a ranking-point category. Actual prize money, field size and tournament conditions vary by event and season.
The ATP Rankings Are Not a Career-Earnings List
Rankings are based on eligible competitive results under current rules. They do not rank players by salary, endorsements, popularity or total career prize money.
Final Answer
ATP stands for Association of Tennis Professionals. It represents players and tournaments within a shared governance system, operates the main men’s tour and Challenger circuit, and publishes the official men’s professional rankings.
The key limitation is equally important: the ATP does not run every part of men’s tennis. The ITF, Grand Slam tournaments, national bodies and other event organizers retain their own responsibilities within the sport.
