Nguyen Thuy Hanh is a human rights defender from Ha Noi. She founded the 50K Fund in 2017 to support for the families of unjustly detained persons across Viet Nam. She was arrested on 7 April 2021 and charged for “making, storing, or spreading information, materials or items for the purpose of opposing the State of the Socialist Republic of Viet Nam”, carrying a potential prison sentence of between five and 20 years. Earlier, her account at Vietcombank was reportedly blocked in 2020 after she raised about 500 million Vietnamese dong (US $21,600) to support the family of Le Dinh Kinh, the elderly leader of the Dong Tam commune, who was shot dead by security forces during a police raid on Dong Tam in Jan. 9, 2020 amid a long-running land dispute that landed many of his family members in jail. According to local groups, she is the 6th activist being arrested for helping Dong Tam land petitioners.

Nguyễn Thúy Hạnh had been previously attacked in 2019.
