The Hopman Cup was an international eight-team indoor hardcourt tennis tournament that played mixed-gender teams on a country-by-country basis. It was held in Perth, Western Australia each year from 1989 to 2019, before being replaced on the calendar in 2020 by the now defunct ATP Cup. It is set to return in July 2023 in Nice, France. Format Unlike other major international team tennis tournaments such as the Davis Cup and the Fed Cup, which are for men or women only, the Hopman Cup is a mixed competition in which male and female players are on combined teams and represent their countries. Players are invited to attend and national coaches are not involved in selecting teams. The tournament is a sanctioned official event in the calendar of the International Tennis Federation (ITF) but, while individual player results are tallied, they are not regarded as official ATP matches or included in the calculation of ATP or WTA rankings. Eight nations are selected annually to compete in the Hopman Cup. The "last" team may be decided by play-offs between several nations before competition begins. For the 2007 Hopman Cup however, this did not occur, due to the Asian Qualifying Tournament creating the eighth team. Each team consists of one male player and one female player. Each match-up between two teams at the event consists of: one women's singles match one men's singles match one mixed doubles match The eight competing teams are separated into two groups of four (with two teams being seeded) and face-off against each of the other three teams in their group in a round-robin format. The seedings ensure that each group has approximately similar strength. The top team in each group then meet in a final to decide the champions. If a player is injured then a player of a lower ranking of that nation may be the substitute. The winning team receives a silver cup perpetual trophy and through 2013 the winning team members were presented with distinctive individual trophies in the shape of a tennis ball. History The Hopman Cup was created in 1989. The championship is named in honour of Harry Hopman (1906–1985), an Australian tennis player and coach who guided the country to 15 Davis Cup titles between 1938 and 1969. From the time the Hopman Cup was founded in 1989, it was attended each year by Hopman's widow, his second wife Lucy, who
