Nevada is a state in the western, mountain west, and southwestern regions of the United States. Nevada is the 7th most extensive, the 35th most populous, and the 9th least densely populated of the 50 United States. Over two-thirds of Nevada's people live in one single county, Clark County, which contains the Las Vegas–Paradise metropolitan area, where the state's three largest incorporated cities are located.

Nevada is largely desert and semiarid, with much of it located within the Great Basin. Areas south of the Great Basin are located within the Mojave Desert, while Lake Tahoe and the Sierra Nevada mountains lie on the western edge. Approximately 86% of the state's land is owned by the U.S. federal government under various jurisdictions, both civilian and military.

Nevada is officially known as the "Silver State" due to the importance of silver to its history and economy. It is also known as the "Battle Born State" because it achieved statehood during the Civil War and the "Sagebrush State" for the native eponymous plant.
