List of ATP number 1 ranked doubles tennis players

The ATP rankings by the Association of Tennis Professionals (ATP) are the merit-based system for determining the rankings in men's tennis. In doubles, the top-ranked team is the pair who, over the previous 52 weeks, has gathered the most ATP rankings points. Points are awarded based on how far a team advances in tournaments and the category of those tournaments. The ATP has used a computerized system for determining doubles rankings since 1976. An updated rankings list is released at the beginning of each week.

Since the introduction of the ATP rankings the method used to calculate a player's ranking points has changed several times. As of 2017,^[update] ranking is based on calculating, for each player, his total points from his best 18 results from all eligible tournaments, including the ATP Finals (Doubles) played in the 52-week ranking period. For entry purposes there are no mandatory events, however, once a player is accepted in the main draw of one of these 12 tournaments, as a direct acceptance, a qualifier or a lucky loser or having accepted a wildcard, his result in this tournament shall count for his ranking, whether or not he participates.^[1]
