Mary Eva Hastings Morris (9 April 1873 – 11 July 1925) was a Welsh doctor and suffragist. Born in Dolgellau, she grew up in Malta, before returning to Wales to study medicine at the University College of Wales in Aberystwyth. She went on to become the first female doctor from Aberystwyth. After spells working at Great Ormond Street Children's Hospital in London, the North Devon Infirmary, and Bristol Royal Hospital for Sick Children and Women, Morris moved to Bath, where she worked as a medical inspector.
