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.
Jimmy Connors finished the year as ATP world No. 1 for the first time in his career. Connors won seven titles during the season, including three majors at the Australian Open, Wimbledon Championships, and the US Open (though the Australian Open was a Group B event rather than a Triple Crown event like the other majors).
Guillermo Vilas was the 1974 Grand Prix No. 1. Vilas won seven tournaments during the season, including the Masters Grand Prix.
