1920 International Lawn Tennis Challenge

The 1920 International Lawn Tennis Challenge, more commonly known as the Davis Cup, was the 15th edition of the major international team event in men's tennis. Six nations competed for the right to challenge holders Australasia. The Netherlands joined the competition for the first time.

The initial draw consisted of four countries and drew the United States against France and the Netherlands against Great Britain. The applications of Canada and South Africa were received after the deadline but their entries were accepted by the other countries and subsequently a new draw was made.

"Big Bill" Tilden and "Little Bill" Johnston made their debut for the United States, and would not lose a rubber the entire tournament. In the Challenge Round, they reclaimed the cup from Australasia. The final, in honor of Anthony Wilding, was played at the Domain Cricket Club in Auckland, New Zealand on 30 December - 1 January 1921.
