Tennis was part of the Summer Olympic Games program from the inaugural 1896 Summer Olympics, but was dropped after the 1924 Summer Olympics due to disputes between the International Lawn Tennis Federation and the International Olympic Committee over how to define amateur players. After two appearances as a demonstration sport in 1968 and 1984 (with a U-21 age limit), it returned as a full medal sport at the 1988 Summer Olympics open for all players regardless of their age and status and has been played at every summer Games since then. In 1896, 1900, 1904, 1988, 1992, semifinal losers shared bronze medals. In all other years, a playoff match for the bronze medal was staged.

Andy Murray is the only player to have won two singles gold medals, and the only singles player to have retained the Olympic title. Nicolás Massú, Venus Williams, and Serena Williams are the only players in the Open Era to win both the singles and same-sex doubles tournaments at one Games, doing so in 2004, 2000, and 2012 respectively.A player who wins an Olympic or Paralympic gold medal and all four majors in the same year is said to have won a Golden Slam. As of 2021, Steffi Graf is the only player to done so through the Olympic gold. In 2021, wheelchair tennis players Diede de Groot and Dylan Alcott did so through Paralympic gold.
