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., 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.

History

Before the 1980 census, Nevada was represented by a single at-large congressional district. As a result of the 1980 redistricting cycle, Nevada was split into two districts.
From 1983 to 1993, the 1st district included most of Clark County. From 1993 to 2003, it covered the county's center, the Las Vegas Valley, while rest of the county and state and were in the 2nd district.
The 2000 census showed further population growth, and the redistricting cycle created Nevada's 3rd congressional district, which included most of Henderson, North Las Vegas, Summerlin, and much of unincorporated Clark County.
The 2010 census and its redistricting cycle gave Nevada its 4th congressional district, further condensing the 1st district towards the urban core of Las Vegas.
The 2020 census and its redistricting cycle moved Henderson, the second largest city in Nevada, from the 3rd to the 1st district.

For the 118th and successive Congresses, the district contains all or portions of the following counties and communities:
