The 2021 ATP Cup was the second edition of the ATP Cup, an international outdoor hard court men's team tennis tournament held by the Association of Tennis Professionals (ATP). It was held with 12 teams at Melbourne Park in Australia, from 2 to 7 February 2021.[1][2]
It was originally supposed to take place with 24 teams in Brisbane, Perth and Sydney from 1 to 10 January 2021, but was changed due to the impact of the COVID-19 pandemic.[3]
Following a case of COVID-19 in the tournament's quarantine hotel, all matches scheduled for 4 February have been suspended.[4]
Team Serbia was the defending champion, but got eliminated in the group stage. Team Russia won the tournament, defeating Italy 2–0 in the final.[5][6]
