Mount Olivet Cemetery is a cemetery in Salt Lake City, Utah. It was established on May 16, 1874 by an act of the U.S. Congress which granted 20 acres of land for public use as a cemetery. The first use of the cemetery was in 1877. The cemetery land originally consisted of exactly 20 acres and was part of the U.S. Army's Camp Douglas military reservation. Since that time, the allotment has been expanded and contracted; the present cemetery is approximately 80 acres.
