The outdoor women's singles competition at the 1912 Summer Olympics was part of the tennis program for the games.

[1] The event was won by Marguerite Broquedis of France, the nation's first victory in the women's singles.

Dorothea Köring of Germany took silver and Molla Mallory of Norway earned bronze; both nations were making their debut in women's singles.

[1] Reigning Olympic champion Dorothea Douglass Lambert Chambers had won at Wimbledon in 1903, 1904, 1906, 1910, and 1911 (and would win two more times after the Games); she would have been heavily favoured if she had returned.

France made its second appearance, matching Great Britain as the two nations that had competed in two of the three editions of the women's singles tournament to that point.
