The 1974 Commercial Union Assurance Grand Prix was a professional 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. The circuit consisted of the four modern Grand Slam tournaments and open tournaments recognised by the ILTF. The season-ending Commercial Union Assurance Masters and Davis Cup Final are included in this calendar but did not count towards the Grand Prix ranking.

Schedule The Grand Prix circuit was scheduled from May until December so that it would not to conflict with the competing World Championship Tennis circuit which ran from January until early May.
