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 miss 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.
