Dame Frances Mary Ashcroft, DBE, FRS, FMedSci (born 1952) is a British geneticist and ion channel physiologist. She is Royal Society GlaxoSmithKline Research Professor at the University Laboratory of Physiology at the University of Oxford. She is a fellow of Trinity College, Oxford and is a director of the Oxford Centre for Gene Function. Her research group has an international reputation for work on insulin secretion, type II diabetes and neonatal diabetes. Her work with Professor Andrew Hattersley has helped enable children born with diabetes to switch from insulin injections to tablet therapy.
After attending Talbot Heath School Ashcroft gained a degree in Natural Sciences, and then a PhD in zoology from Cambridge in 1978. Ashcroft then did post-doctoral research at the University of Leicester and the University of California at Los Angeles.
Ashcroft's research focuses on ATP-sensitive potassium (KATP)channels and their role in insulin secretion. Ashcroft is working towards explaining how a rise in the blood glucose concentration stimulates the release of insulin from the pancreatic beta-cells, what goes wrong with this process in type 2 diabetes, and how drugs used to treat this condition exert their beneficial effects. Ashcroft has authored a few science and popular science books based on ion channel physiology:
- Ion Channels and Disease: Channelopathies on channelopathic diseases 
- Life at the Extremes: The Science of Survival 
- The Spark of Life: Electricity in the Human Body
Honours and awards
Ashcroft was elected a Fellow of the Royal Society in 1999. In 2007 Ashcroft was awarded the Walter B. Cannon Award, the highest honour bestowed by the American Physiological Society. She was one of five 2012 winners of the L'Oreal-UNESCO Award for Women in Science.
