Yolande Heslop-Harrison is a British botanist known for her work on carnivorous plants, ecology, and plant reproduction including stigma morphology. She shared the 1982 Darwin Medal with her husband Jack Heslop-Harrison.
She attended Central Newcastle High School for Girls. She did her undergraduate studies University of Durham and graduated with high honors in 1941. She earned her Ph.D. at King's College, Durham University (now Newcastle University).
