Mary Elizabeth Bennett Ritter (June 7, 1860 – March 17, 1949) was an American physician and an advocate for women's rights and public health issues in Berkeley, California.
She was known as a pioneer in her time because women were largely excluded from medical training and employment.
Despite restricted access, Ritter built a successful private practice.
She also advocated for women in medical professions, training for nurses, and sanitation standards in hospitals and doctor's offices.
She helped start the Pacific Dispensary for Women and Children, free clinics for poor women and children.
In 1933, she published her autobiography, More Than Gold in California.
