Tennis at the 2012 Summer Olympics – Qualification

Qualification for tennis at the 2012 Summer Olympics in London, United Kingdom, was determined not by any form of qualifying tournament, but by the rankings maintained by the Association of Tennis Professionals (ATP) and the Women's Tennis Association (WTA).

Qualifying criteria
The main qualifying criteria were the ATP and WTA ranking lists as of 11 June 2012. The players entering were formally submitted by the International Tennis Federation. The ATP and WTA rankings were based on performances from the previous 52 weeks, and there were several tournaments in the two-month period between the time of the rankings being frozen for entry and the beginning of the tennis events at the Olympics. Players must have also made themselves available for two Fed/Davis Cup events from 2009–2012, one of which must have taken place in 2011–2012, and had a good standing with their National Olympic Committee.

Each National Olympic Committee (NOC) could enter up to six men and six women athletes, with a maximum of four entries in the individual events, and two pairs in the doubles events. Any player in the world's top 56 was eligible, and NOCs had the option to enter players of a lower rank. Athletes were able to compete in both singles and doubles events. Doubles players within the top 10 doubles rankings on 11 June were eligible to bring any player provided that player had any doubles or singles ranking, and as long as the number of players from the same country did not surpass the total of six.
