Cork Prison (Irish: Príosún Chorcaí) is an Irish penal institution on Rathmore Road, Cork City, Ireland. It is a closed, medium security prison for males over 17 years of age, with capacity for 275 prisoners. It is immediately adjacent to Collins Barracks and near the Glen area of the city. While the current prison facility was built and opened as a €45m development in 2016, it replaced an existing 19th century prison facility on the same road.
