Lehi ( LEE-hy) is a city in Utah County, Utah, United States. It is named after Lehi, a prophet in the Book of Mormon. The population was 47,407 at the 2010 census, up from 19,028 in 2000. A more recent 2019 estimate reports a population of 69,724. The rapid growth in Lehi is due, in part, to the rapid development of the tech industry region known as Silicon Slopes. The center of population of Utah is located in Lehi.
Lehi is part of the Provo–Orem Metropolitan Statistical Area.
A group of Mormon pioneers settled the area now known as Lehi in the fall of 1850 at a place called Dry Creek in the northernmost part of Utah Valley. It was renamed Evansville in 1851 after David Evans, a local bishop in The Church of Jesus Christ of Latter-day Saints (LDS Church). Other historical names include Sulphur Springs and Snow's Springs.
The land was organized into parcels of 40 acres (160,000 m2), and new settlers received a plot of this size until the entire tract was exhausted. There was little water to irrigate the rich soil, so it became necessary to divert a portion of American Fork Creek.
