🎾Teams

Tennis has no club league like football or baseball. Players earn ranking points under their own names, hire their own teams, and tournaments move across continents. Yet the bodies that actually organize the sport are unmistakable: national federations and associations that own majors, develop juniors, send players to team competitions and build courts. The US Open is a USTA property; Roland Garros sits in a stadium the French Tennis Federation built in 1928 to defend the Davis Cup; the Australian Open runs at Melbourne Park under Tennis Australia. The 12 programs below are, in that sense, this sport's franchises.

Four metrics are applied equally to all twelve. Davis Cup titles in men's team tennis; Billie Jean King Cup titles in women's team tennis (formerly the Fed Cup); the number of players who reached ATP or WTA singles world No. 1 while representing that nation; and Olympic singles gold medals since tennis returned as a full medal sport at Seoul 1988. Team records are through the end of the 2024 season. Where state forms changed, as with Czechia and Russia, ITF-recognized successor records are included. Bars compare only within this dozen — a full bar means the list maximum.
