Mary Dilys Glynne OBE (19 February 1895 – 9 May 1991) was a British plant pathologist and mountaineer.

She was the first plant pathologist at Rothamsted Experimental Station and was particularly interested in soil-based fungal diseases including potato wart, eyespot in wheat and take-all. She discovered a method for identifying varieties of crop resistant to these fungal diseases and proved that methods such as crop rotation only perpetuated the problem. Her research led to increased yields in agriculture, which was of particular note during World War II, and was appointed an OBE for her services to agriculture.

Glynne was also a passionate mountaineer, climbing a number of famous Alpine peaks. She was the second person, the first woman, to climb Mount Spencer in New Zealand.
