The National Society of the Sons of Utah Pioneers (SUP) is an organization dedicated to preserving the legacy and studying the history of the Mormon Pioneers of Utah and the West. The organization is open to "All good men of every age and circumstance who have an interest in the early Utah Pioneers. It is not necessary to have pioneer ancestry to join." In 1982 a national headquarters building was completed in the East Mill Creek area of Salt Lake City. Administrative offices and a print library are housed there, as well as meeting rooms for local and national events.
