Nevada's 1st congressional district

Nevada's 1st congressional district is a congressional district for the United States House of Representatives in the U.S. state of Nevada. The district covers a portion of Clark County east of Interstate 15 and south of Nellis Air Force Base. It includes parts of the city of Las Vegas and Enterprise, most of Henderson, Paradise, Boulder City, Sunrise Manor, and Winchester as well as all of Boulder City, Whitney and Nelson.

Dina Titus, a Democrat and retired UNLV professor, has served as the district's representative since 2013. From 2008 to 2010, Titus represented part of the same geographic area as Nevada's 3rd district, which was redrawn as part of the 2010 redistricting cycle.

Since it was created in 1982 from an at-large district, the only Republican to represent the 1st district has been John Ensign for two terms from 1995 until 1999.

Since the 2020 census resulted in redistricting, the district has been considered competitive due to demographic changes and the overall political climate. However, Democrats have held the seat since. As of February 2025, the 2026 Cook Political Report analysis of House races across the country classified the 1st district as competitive with Democrats having a two point advantage over Republicans.
