The Mbweni Ruins, situated near Stone Town on Zanzibar Island in Tanzania, are historical remnants that offer insight into the island's past. These ruins are the remains of a complex that once served as a missionary settlement, school, and plantation during the 19th century.

Originally established by the Church Missionary Society (CMS) in the mid-19th century, the Mbweni Ruins included a mission, a school for freed slave girls, and a plantation where the girls were taught agricultural and domestic skills. The site also had a botanical garden that was home to various exotic plants and trees. The ruins include parts of the old buildings, such as the mission house, classrooms, dormitories, and other structures, which provide glimpses into the historical significance of the site.
