Keystone Mineral Springs is an historic mineral water bottling facility on Keystone Spring Road in Poland, Maine. Located along the former right-of-way of Keystone Spring Road in eastern Poland, the facility consists of two structures, a spring house built c. 1885 and a bottling house built in 1929. The facilities are, along with the more well-known Poland Spring Bottling Plant and Spring House, the only known surviving elements of the early period of mineral water bottling in Maine.
