Mary Carpenter (3 April 1807 – 14 June 1877) was an English educational and social reformer. The daughter of a Unitarian minister, she founded a ragged school and reformatories, bringing previously unavailable educational opportunities to poor children and young offenders in Bristol.

She published articles and books on her work and her lobbying played a role in the passage of several educational acts in the mid-nineteenth century. She was also the first woman to have a paper published by the Statistical Society of London. She addressed many conferences and meetings and became known as one of the foremost public speakers of her time. Carpenter was active in the anti-slavery movement; she also visited India, visiting schools and prisons and working to improve female education, establish reformatory schools and improve prison conditions. In later years she visited Europe and America, carrying on her campaigns of penal and educational reform.
