Tien Fuh Wu or Tien Fu Wu (around 1886 – 1975) was a pioneer in the anti-human trafficking movement in San Francisco, California. After being rescued in childhood from her role as a mui tsai (a child servant), she worked for decades to free Chinese immigrant women and girls from sexual slavery and indentured servitude. As the long-time aide to Donaldina Cameron, Wu dedicated her life to helping the residents of the Presbyterian Mission Home, a rescue mission in Chinatown.
