The Billie Jean King Cup is the premier international team competition in women's tennis, launched as the Federation Cup in 1963 to celebrate the 50th anniversary of the International Tennis Federation (ITF). The name was changed to the Fed Cup in 1995, and changed again in September 2020 in honor of former World No. 1 Billie Jean King. The Billie Jean King Cup is the world's largest annual women's international team sports competition in terms of the number of nations that compete. The current chair is Katrina Adams.

The 2020–21 Davis Cup was the 109th edition of the Davis Cup, a tournament between national teams in men's tennis. It was sponsored by Rakuten. For this edition, the format of the cup was changed. The new format saw the creation of a Davis Cup World Group I and World Group II which was played on a worldwide basis and replaced the regional Group I and Group II. As a result, the Davis Cup nations ranking was no longer used to determine which group a nation was played in. Previous the 2019, and the 2021 finals host Spain were the defending champions. Due to the COVID-19 pandemic, on 26 June 2020 the ITF announced that the 2020 finals would take place from 22 until 28 November 2021. In addition, 24 World Group I and World Group II ties were postponed to March and September 2021, and the 2020 regional Group III and Group IV events were also postponed to 2021. The 18 nations that qualified for the finals kept their standing for the next year.
