The Hopman Cup is an international tennis tournament that plays mixed-gender teams on a country-by-country basis. It was first held in Perth, Western Australia each year from 1989 to 2019, played on indoor hardcourt, before being replaced on the calendar in 2020 by the now defunct ATP Cup. The tournament was played in an eight-team format, with the exception for the years 1990-1995, with twelve teams competing. It returned in July 2023 in Nice, France, played on outdoor clay, with six teams invited to participate.

Tennis is a racket sport that is played either individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball validly will not gain a point, while the opposite player will.
