The 1973 Commercial Union Assurance Grand Prix was a tennis circuit administered by the International Lawn Tennis Federation (ILTF) which served as a forerunner to the current Association of Tennis Professionals (ATP) World Tour and the Women's Tennis Association (WTA) Tour.^[1] The circuit consisted of the four modern Grand Slam tournaments and open tournaments recognised by the ILTF. Bonus points were awarded to players who were nominated to play in certain 1973 Davis Cup ties and who missed tournaments through competing in those ties.^[2] The Commercial Union Assurance Masters is included in this calendar but did not count towards the Grand Prix.

Grand Prix points system

The tournaments listed above were divided into four groups. Group AA consisted of the Triple Crown – the French Open, the Wimbledon Championships and the US Open – while the other tournaments were divided into Groups A, B and C by prize money and draw size. Points were allocated based on these groups and the finishing position of a player in a tournament. No points were awarded to first round losers and ties were settled by the number of tournaments played. The points allocation is listed below:

**Group AA**
Champion: 100 Runner-up: 75 Semifinalist: 50 Quarterfinalist: 25 Fourth Round: 12 Third Round: 6 Second Round: 3

ATP rankings

On 23 August 1973 the Association of Tennis Professionals published its first list of computer rankings, using points averages rather than points totals in their calculations. These are the ATP rankings of the top twenty singles players in the first list^[4] and at the end of the 1973 season,^[5] with numbers of ranking points, points averages, numbers of tournaments played, year-end rankings in 1973, highest and lowest positions during the season and number of spots gained or lost from the first rankings to the year-end rankings.
