Lincoln County is a county in the U.S. state of Nevada. As of the 2020 census, the population was 4,499,  making it the fourth-least populous county in Nevada. Its county seat is Pioche.  Like many counties in Nevada, it is dry and sparsely populated, though notable for containing the Area 51 government Air Force base.
Lincoln County was established in 1866 after Congress enlarged Nevada by moving its state line eastward and southward at the expense of Utah and Arizona territories.  It is named after Abraham Lincoln, the 16th President of the United States.  Original legislation called for the creation of a "Stewart County", after Nevada Senator William M. Stewart, but this was later changed in a substitute bill. Crystal Springs was the county's first seat in 1866, followed by Hiko in 1867 and Pioche in 1871.
Lincoln County initially included a ranch village and railroad siding named Las Vegas. However, that siding, which led to the future city of Las Vegas, was separated from Lincoln County upon the founding of Clark County effective July 1, 1909, by act of the Nevada Legislature. 
Area 51 is in Lincoln County and the county sheriff acts in proxy for the perimeter security forces.
