Mormon folklore is a body of expressive culture unique to members of the Church of Jesus Christ of Latter-day Saints and other sects of Mormonism. Mormon folklore includes tales, oral history, popular beliefs, customs, music, jokes, and material culture traditions. In folklore studies, Mormons can be seen as a regional group, since the core group of Mormon settlers in Utah had a common religion and had to modify their surroundings for survival. This historical regional area includes Utah, Southeastern Idaho, parts of Wyoming and eastern Nevada, and a few towns in eastern Arizona, southern Alberta, northwestern New Mexico, southern Colorado, and northern Chihuahua, Mexico.

Pioneer Day is an official holiday celebrated on July 24 in the American state of Utah, with some celebrations taking place in regions of surrounding states originally settled by Mormon pioneers. It commemorates the entry of Brigham Young and the first group of Mormon pioneers into the Salt Lake Valley on July 24, 1847, where the Latter-day Saints settled after being forced from Nauvoo, Illinois, and other locations in the eastern United States. Parades, fireworks, rodeos, and other festivities help commemorate the event. Similar to July 4, many local and all state-run government offices and many businesses are closed on Pioneer Day.
