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.

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.

The tournaments of the Grand Prix circuit were divided into five groups. Group TC consisted of the Triple Crown events—the French Open, the Wimbledon Championships, and the US Open—while the other tournaments were divided into four other groups—AA, A, B, and C—by prize money and draw size. Group AA tournaments had a minimum prize money of $100,000 while the minimum for Group A and Group B tournaments was $75,000 and $50,000 respectively. 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. Grand Prix points were also allocated to doubles results for the first time this year and are listed in brackets in the points allocation below:

In addition a player could earn ranking points for participating in the Davis Cup team competition if the matches coincided with a Grand Prix tournament.

These are the ATP Rankings of the top twenty singles players at the end of the 1973 season and at the end of the 1974 season, with numbers of ranking points, points averages, numbers of tournaments played, year-end rankings in 1974, highest and lowest positions during the season and number of spots gained or lost from the first rankings to the year-end rankings.
