The 1911 International Lawn Tennis Challenge was the tenth edition of what is now known as the Davis Cup, named after the American tennis player Dwight F. Davis. After no country decided to challenge Australasia in 1910, only the British Isles and the United States would challenge for the Cup, for the third straight edition. Also for the third straight edition, the Americans would beat the British to earn the right to play for the Cup, and for the third straight edition, the Aussies would beat the Americans for the title.

The Davis Cup is the premier international team event in men's tennis. It is run by the International Tennis Federation (ITF) and is contested annually between teams from over 150 competiting countries, making it the world's largest annual team sporting competition. It is described by the organisers as the "World Cup of Tennis", and the winners are referred to as the World Champions. The competition began in 1900 as a challenge between Great Britain and the United States. By 2023, 155 nations entered teams into the competition.
