The 2026 United Cup was the fourth edition of the United Cup, an international outdoor hard court mixed-gender team tennis tournament that was held by the Association of Tennis Professionals (ATP) and the Women's Tennis Association (WTA). Serving as the opener for the 2026 ATP Tour and the 2026 WTA Tour, it happened from 2 to 11 January 2026 at two venues in the Australian cities of Perth and Sydney. It was offering both ATP rankings and WTA rankings points to its players: a player was able to win a maximum of 500 points.

Team Poland, captained by Mateusz Tarczyński, won the title after defeating Team Switzerland 2–1 in the final, claiming their first United Cup title. The winning team consisted of Iga Świątek, Hubert Hurkacz, Jan Zieliński, Katarzyna Kawa, Daniel Michalski and Katarzyna Piter. It was Poland's third United Cup final and first title.

Team United States were the defending champions but were defeated in the semifinal by team Poland.

Belinda Bencic of Team Switzerland was named the MVP of the tournament.

Format Both cities hosted three groups of three countries in a round robin format. Each tie consisted of one men's and one women's singles match, and one mixed doubles match.

The six group winners and the best runner-up in each city advanced to the quarterfinals.

Qualification 18 countries qualified as follows: Five countries qualified based on the ATP ranking of their number one ranked singles player. Five countries qualified based on the WTA ranking of their number one ranked singles player. Eight countries qualified based on the combined ranking of their number one ranked ATP and WTA players.

In exchange for being the host nation, Australia was guaranteed one of the spots reserved for teams with the best combined ranking if it would have failed to qualify on its own.

Teams will feature up to three players from each tour.

Venues Perth and Sydney each were hosting three groups of three countries in a round robin format and two quarterfinals. Sydney hosted the semifinals and the final on the last two days of the tournament.

Ranking of second-placed teams The best runner-up quarter-final spot was determined by the number of ties won and the number of ties played. In a tie between three teams, the team having played fewer total matches (singles and mixed doubles) would be eliminated and, if still tied then the team with the most match would win (singles and doubles). If still tied, then the ranking would be determined by, in order: 1) the highest percentage of matches won, 2) the highest percentage of sets won, and 3) the highest percentage of games won.
