The maniple is a liturgical vestment used primarily within the Latin Rite of the Catholic Church, and occasionally by some Anglo-Catholic and Lutheran clergy. It is an embroidered band of silk or like fabric that is hung over the left arm. It is used only during Mass, and it is always of the same liturgical colour as other Mass vestments.

Vestments are liturgical garments and articles associated primarily with the Christian religion, especially by Eastern Churches, Catholics, Lutherans, and Anglicans. Many other groups also make use of liturgical garments; among the Reformed (Calvinist) Churches this was a point of controversy in the Protestant Reformation and sometimes since, in particular during the ritualist controversies in the Church of England in the 19th century.
