Missionaries of The Church of Jesus Christ of Latter-day Saints (LDS Church)—widely known as
Mormon missionaries—are volunteer representatives of the LDS Church who engage variously in
proselytizing, church service,
humanitarian aid, and community service. Mormon missionaries may serve on a full- or part-time basis depending on the assignment, and are organized geographically into
missions. The mission assignment could be to any one of the
418 missions organized worldwide.
