The United Baptist Woman’s Missionary Union, or U.B.W.M.U is a Maritimes-based Baptist missionary group which aims to encourage the formation of women’s missionary bands in the maritime provinces and perform missionary work abroad, chiefly in India and Bolivia. The groundwork for the foundation of this organization was laid in 1905 when two Baptist groups in the Maritimes, the Free Baptists and the Maritime Baptists, became a combined body with the name United Baptists. In the following year the women’s missionary societies of the two groups were united as well, and together they formed the U.B.W.M.U. An annual meeting of this organization was held in Bridgetown in August 1906. Here the specifics of the union between the two missionary societies were worked out, and the basis of the U.B.W.M.U. was set. For its first year of operation, the executive committees of both groups were amalgamated into the Executive Board of the U.B.W.M.U. The first official annual meeting of this union was held at Sussex, New Brunswick, on August 22 and 23 1907. 1907 was also the year they were officially incorporated.

The primary goals of the union were encouraging the formation of local missionary bands and performing missionary work abroad. The union also published a monthly bulletin named “Tidings”, which provided updates on missionary work being done within and outside the maritime provinces and news from recent meetings. Starting in May 1912 the U.B.W.M.U. was involved with the then newly formed Federation of Canadian Baptist Mission Bands, which was formed from a union between mission bands in Ontario, Quebec, and the Maritime Provinces. Going forward all missionary work abroad was done through this organization.

The efforts of the U.B.W.M.U. continue today under their new name of Atlantic Baptist Women (registered 2017). Today the organization supports local church activities and community services, children’s education, and global missionary work.
