Thiri Pyanchi Yin May FRCS FRCP FRCOG (Burmese: ရင်မေ, pronounced [jìɰ̃ mè]; September 1900 – 29 September 1978) was a Burmese physician and educator. She was the first Burmese obstetrician and gynecologist, and the first person to perform the Caesarian section in British Burma. She is also known for her research on amoebic vaginitis, known as May's disease.

Yin May founded the country's main maternity hospital during the Japanese occupation (1942–1945), and she co-founded the wartime medical and nursing schools (1943–1945). After the war, she served as the head of Lady Dufferin Maternity Hospital from 1946 to 1959, and the head of the Department of Obstetrics and Gynecology of the Faculty of Medicine of Rangoon University from 1947 to 1959. Under her leadership, Dufferin became a maternity hospital recognized by the Royal College of Obstetricians and Gynaecologists in 1957.
