The Tonkin Free School (Vietnamese: Đông Kinh Nghĩa Thục, 東京義塾) was a short-lived but historically significant educational institution in Hanoi that aimed to reform Vietnamese society under the French protectorate during the beginning of the 20th century.
It stemmed from the movement of the same name, which aimed to modernize Vietnamese society by abandoning Ruism and adopting new ideas from the West and Japan.
The schools offered free courses to anyone who wanted to learn about the modern spirit.
The teachers at the school at 59 Hàng Đàn included Phạm Duy Tốn.
