The Ohio Reformatory for Women (ORW) is a state prison for women owned and operated by the Ohio Department of Rehabilitation and Correction in Marysville, Ohio. It opened in September 1916, when 34 female inmates were transferred from the Ohio Penitentiary in Columbus. ORW is a multi-security, state facility. As of July 2019, 2,394 female inmates were living at the prison ranging from minimum-security inmates all the way up to one inmate on death row. It was the fifth prison in the United States, in modern times, to open a nursery for imprisoned mothers and their babies located within the institution. The Achieving Baby Care Success (ABC) program was the first in the state to keep infants with their mothers.
