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, England from 7–9 June, and the final was played at Worple Road (the former site of the All England Club) in Wimbledon, London, England on 15–18 June.[1] Britain retained the Cup for their fourth championship.[2]
