Lini M. De Vries (July 25, 1905—March 27, 1982), born Lena Moerkerk in Prospect Park, New Jersey, was a Dutch–American author, public health nurse, and teacher. She worked as chief of American Hospital Number 3 on the Madrid-Valencia Road during the Spanish Civil War and later organized health clinics in New Mexico, California, and Puerto Rico. She moved to Mexico in 1949 after her membership in the Communist Party was exposed. In Mexico, De Vries taught medicine and public health to indigenous villagers in the Papaloapan River Basin in Oaxaca; taught anthropology and public health at the University of Veracruz; was a founder of CIDOC, a religious, educational and cultural school; and helped found Cemanahuac, an educational community in Cuernavaca, Mexico.
