Tenis je još na prvim modernim Olimpijskim igrama 1896. u Atini uveden u takmičarski program. Posle OI, takođe u Parizu, 1924. tenis je povučen iz zvaničnog takmičenja, da bi bio vraćen kao demonstracioni sport 1968. u Meksiko Sitiju i 1984. u Los Anđelesu.
Definitivno se vraća kao takmičarski sport 1988. u Seulu...
