Lorenzo Snow Young (1894-1968) was a Mormon architect in Utah.

Lorenzo Snow Young was born on November 16, 1894 in Salt Lake City, Utah to Brigham Morris Young and Celestia Armeda Snow. He was also known as Bing, named after the family dog. Young dropped out of high school as a teen to work for the Oregon Short Line Railroad, where he trained as a draftsman. He later returned to school, graduating from LDS High School in 1917. The following year he joined the United States Army, and served as a communications runner in France.

In 1919 Young was discharged from the Army and decided to travel to New York to study architecture at the Pratt Institute. He then continued his studies at Columbia University and the University of Pennsylvania, graduating from the latter in 1923. Amid his studies he returned briefly to Utah to marry Catherine Aleine Margetts on September 17, 1920. They eventually had four children.

After completing his architecture degree, Young worked briefly in Philadelphia before relocating to Utah. He was initially employed by the Church of Jesus Christ of Latter-day Saints, but later started a professional practice with Edward O. Anderson. In 1936 Arnold Ehlers joined the firm, and a year later Anderson departed. Over the course of his career he designed Kingsbury Hall on the University of Utah campus, the J. Reuben Clark Jr. Library, and other notable public buildings across Utah.

During World War II he joined the Army, serving between 1943 and 1946. He was stationed at Utah's Fort Douglas, and was also in charge of determining the costs of converting military buildings to civilian uses in the western region.

Young died unexpectedly on March 26, 1968 in Salt Lake City, Utah following back surgery.
