The 1912 World Hard Court Championships – Women's singles was a tennis competition held as part of the inaugural World Hard Court Championships (WHCC) sanctioned by the International Lawn Tennis Federation (ILTF). The tournament took place from June 1 to June 9, 1912, at the Stade Français in Saint-Cloud, Paris. The WHCC was established to provide a world championship venue for play on clay surfaces, which were referred to as "hard courts" to distinguish them from the grass courts used at Wimbledon.
The inaugural women's singles event featured a draw of international competitors. In the final, Marguerite Broquedis of France defeated Mieken Rieck of Germany in three sets, with a final score of 6–3, 0–6, 6–4. With this victory, Broquedis became the first women's singles champion of the World Hard Court Championships. This win occurred shortly before her success at the 1912 Summer Olympics, where she also won a gold medal in women's singles.
The tournament is historically recognized as one of the three major world championships of tennis that existed prior to the standardization of the Grand Slam titles in 1924. The event continued annually, with interruptions during World War I, until it was eventually discontinued after 1923 when the ILTF granted "Major" status to the French Championships (now the French Open).
