Brigham Morris Young (January 18, 1854–February 20, 1931 (aged 77)) was one of the founders of the Young Men's Mutual Improvement Association (YMMIA), the predecessor to the Young Men program of The Church of Jesus Christ of Latter-day Saints (LDS Church). Young was the son of Brigham Young and one of his wives, Margaret Pierce. In 1875, Morris Young served a mission for the LDS Church in the Hawaiian Islands. Shortly after returning from this mission, he was asked by his father to organize the YMMIA along with Junius F. Wells and Milton H. Hardy.
