The 1977 Colgate-Palmolive Grand Prix was a professional tennis circuit administered by the International Lawn Tennis Federation (ILTF, later the ITF) 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 Colgate-Palmolive Masters is included in this calendar but did not count towards the Grand Prix ranking. Colgate-Palmolive was the new tour sponsor, taking over from Commercial Union. Guillermo Vilas won the Grand Prix circuit, having accumulated the most points (2,047), and received the largest share from the bonus pool ($300,000). The top eight points ranked singles players as well as the top four doubles teams qualified for the season-ending Masters tournament
