Ragna Marie Jenny Rask-Nielsen née Jensen (1900–1998) was a Danish biochemist and medical researcher. After she earned a PhD with a dissertation on the development of carcinogenic tumors in mice in 1948, she carried out laboratory-based studies on antibody-producing tumors. In 1963, her groundbreaking work on viruses causing cancerous lymphoma was published in the journal Nature. When she died at the age of 97, she left her large fortune to a research foundation.
