1906 International Lawn Tennis Challenge

The 1906 International Lawn Tennis Challenge was the sixth edition of what is now known as the Davis Cup. As defending champions, the British Isles team played host to the competition. For the first time, the ties were not all played at the same location. The "World Group" ties were played at the Newport Athletic Club in Newport, Monmouthshire, United Kingdom from 7–9 June, and the final was played at Worple Road in Wimbledon, London, United Kingdom on 15–18 June. Britain retained the Cup for their fourth championship.
