2021 Laver Cup

The 2021 Laver Cup was the fourth edition of the Laver Cup, a men's tennis tournament between teams from Europe and the rest of the world. It was held on indoor hard courts at the TD Garden in Boston, United States from 24 until 26 September.

It was originally scheduled for September 2020, but was postponed due to the COVID-19 pandemic to avoid overlapping with the 2020 French Open, which was rescheduled for 20 September to 4 October.

Team Europe captain Björn Borg and Team World captain John McEnroe reprised their roles from 2019.

Team Europe won the title for a fourth consecutive edition.

Player selection
Roger Federer was originally the first player to confirm his participation for Team Europe on 28 February 2020, but withdrew on 15 August 2021 due to a right knee injury.
