The Lutheran Church—Missouri Synod (LCMS) is a conservative Lutheran denomination in the United States, established in 1847 by German immigrants seeking religious freedom. It originated from a group of Saxon immigrants led by Pastor C.F.W. Walther, who became the first president of the Synod. Headquartered in St. Louis, Missouri, the LCMS emphasizes strict adherence to the Bible and the Lutheran confessions as outlined in the Book of Concord.

The Synod operates various ministries, including congregational worship, Christian education, and evangelism. It runs schools from elementary to higher education, focusing on confessional Lutheran teaching. The LCMS is also active in missionary work, reaching out to immigrant communities and providing pastoral training through its seminaries. Additionally, it produces doctrinal publications, educational materials, and worship resources to support its congregations and members. The LCMS serves families and individuals seeking a traditional Lutheran faith experience grounded in historic doctrine.
