Yang Chongrui (Chinese: ???; pinyin: Yáng Chóngruì) was a Chinese obstetrician who is credited with modernising women's healthcare in China.
Her contributions to the field of obstetrics and her training of midwives and nurses led to a significant decrease in deaths relating to pregnancy.
Between 1949 and 1954 the percentage of women dying through childbirth dropped from 0.7% to 0.05%, while infant mortality was reduced from 11.7% to 4.6%.
