The Nevada National Security Sites (N2S2 or NNSS), popularized as the Nevada Test Site (NTS) until 2010, is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about 65 mi (105 km) northwest of the city of Las Vegas.

Formerly known as the Nevada Proving Grounds of the United States Army, the site was acquired in 1951 to be the testing venue for the American nuclear devices. The first atmospheric test was conducted at the site's Frenchman Flat area by the United States Atomic Energy Commission (USAEC) on January 27, 1951. About 928 nuclear tests were conducted here through 1992, when the United States stopped its underground nuclear testing.

The site consists of about 1,350 sq mi (3,500 km2) of desert and mountainous terrain.
