The 1913 International Lawn Tennis Challenge was the 12th edition of what would be called the Davis Cup. With the British Isles winning in 1912, the competition stayed in Europe with seven teams competing in the competition with Canada, Germany and South Africa joining for the first time. In the end, Canada shocked the tennis world by defeating the British Isles 3-2 which was played at Worple Road, London.
Canada, Germany and South Africa all competed for the first time. Belgium returned to the competition for the first time since 1904.
