The Joseph Smith Memorial Building (JSMB), originally called the Hotel Utah, is a social center located on the corner of Main Street and South Temple in Salt Lake City. It is named in honor of Joseph Smith, founder of the Latter Day Saint movement.
It previously housed several restaurants and also functioned as a venue for events, although it was closed in 2023 for extensive renovations, expected to be completed in 2025. Several levels of the building have also been administrative offices for departments of the Church of Jesus Christ of Latter-day Saints (LDS Church), such as FamilySearch.
On January 3, 1978, it was added to the National Register of Historic Places as the Hotel Utah.
