The Chama cha Mariamu Mtakatifu (Community of St. Mary of Nazareth and Calvary), (CMM) is a large Anglican religious order operating within the Anglican Church of Tanzania, and with its headquarters at Masasi, Tanzania.
Female religious were first introduced to Tanzania by clergy missionaries of the Universities' Mission to Central Africa, working in conjunction with the sisters of the Community of the Sacred Passion (CSP).
Today the sisters focus their work on caring for parish churches, administering and teaching in primary schools, and outreach to hospitals, prisons, and the disadvantaged.
They engage in agriculture, and also produce community wares for sale, including vestments, altar breads, and candles.
In 2024 there are twelve convents in total, eleven in Tanzania, and one in Zambia,[1] where the Order is seeking to expand.
