As early as 1854, President Brigham Young sent a missionary to Thailand, then known as Siam. He stayed only four months due to a language barrier.
In the 1950s and before 1961, informal Church services were held intermittently when families lived in Bangkok. The English branch (a small congregation) has functioned continually since 1961 when regular worship services were authorized by the Church.
The Thailand District was organized in 1966. President Gordon B. Hinckley dedicated Thailand for the preaching of the gospel on November 2, 1966. Missionaries were then transferred to the area, which ensured membership growth.
In 1973, Thailand became its own mission. In 1974, Elder David B. Haight dedicated the first meetinghouse. In 1987, three new meetinghouses were dedicated in Bangnaa, Thonburi, and Chiang Mai Branches. In 1995, the Bangkok Stake (diocese) was created.
