The Olympic Tennis Centre is a grouping of tennis courts at the Athens Olympic Sports Complex. It hosted the tennis matches at the 2004 Summer Olympics in Athens, Greece. The centre consists of a main stadium, known as as the Main Court, seating 8,600 fans - though only 6,000 seats were made publicly available during the Olympics - two semifinal courts seating 4,300 spectators - though only 3,200 seats were made publicly available during the Olympics - and thirteen side courts seating 200 observers each. The centre was completed in February 2004 and officially opened on August 2, 2004.

Each of the courts was a hardcourt. The Main Court, in particular, was extremely large by the standards of major tennis competitions, with the seats relatively far removed from the tennis court.
