The Brothers of Our Lady Mother of Mercy (Latin: Congregatio Fratrum B. Mariæ V., Matris Misericordiæ), sometimes called the Brothers CMM or Brothers of Tilburg, is a Catholic lay religious congregation of Pontifical Right for men founded in Tilburg, the Netherlands, in 1844 by Johannes Zwijsen, and initially placed under the leadership of Franciscus Salesius de Beer (1821-1901). The purpose of the congregation was to carry out works of charity and works of mercy. The congregation currently has about 300 members working in 10 countries. In June 2014, Brother Lawrence Obiko was elected as superior general of the congregation. Its members add the nominal letters C.M.M. after their names to indicate membership in the congregation.
