In the U.S. state of Nevada, U.S. Route 95 is a major U.S. highway traversing the state from north to south directly through Las Vegas and providing connections to both Carson City (via US 50) and Reno (via Interstate 80). US 95 is cosigned with Interstate 80 for 95 miles (153 km) between a junction in Churchill County and Winnemucca before heading north into Oregon at McDermitt.

U.S. Route 95 enters Nevada near Cal-Nev-Ari in Clark County and heads north towards Railroad Pass, where it meets US 93. The two routes are then cosigned in the Las Vegas area and east of Henderson, Interstate 515 begins. I-515 is cosigned with US 93/95 for its entire route around eastern Las Vegas. The freeway then heads west into downtown Las Vegas, where it intersects Interstate 15. At the Spaghetti Bowl interchange, US 93 follows I-15 northbound and I-515 ends. US 95 heads west, then north at the Rainbow Curve. The freeway portion then ends and then it becomes a brief four-lane divided highway. US 95 exits Clark County and heads into eastern Nye County, where it briefly enters Esmeralda before meeting US 6 in Tonopah, back in Nye County. US 6/95 leave Tonopah heading west for 41 miles (66 km) until Coaldale, where US 6 splits west towards California and its western terminus in Bishop, California. US 95 then heads northwest towards Hawthorne and Schurz, where ALT U.S. 95 splits west towards US 50, providing an alternate route towards Carson City and Reno. US 95 itself goes north towards Fallon, where it intersects U.S. 50. US 95 meets Interstate 80 and US 95 Alternate near Lovelock. The two routs then run concurrently for 95 miles (153 km) until reaching Winnemucca, where US 95 splits from I-80. North of Winnemucca, US 95 meets the eastern terminus of SR 140, which connects to Lakeview, Oregon (U.S. Route 395) and Klamath Falls, Oregon and the Pacific Northwest. U.S. 95 finally exits Nevada at McDermitt and heads into Oregon.[

US 95 was one of the original U.S. highways in the 1925 Bureau of Public Roads plan.[3] It was commissioned in 1926, but was not extended south into Nevada until 1940. US 95 was routed entirely over existing state highways in Nevada.

The original route was largely the same as today except for some minor realignments and a circuitous detour between Fallon and Winemucca via Fernley.

From the California state line south of Searchlight north to 41 miles (66 km) south of Tonopah, replacing SR 5 (routed concurrently with US 93 and US 466 from Railroad Pass to downtown Las Vegas. From 41 miles (66 km) south of Tonopah north to Schurz, replacing part of SR 3 (routed concurrently with US 6 from Tonopah to Coaldale). Schurz north to Fallon, replacing part of SR 1A. Fallon northwest to Fernley, replacing the western section of SR 2 (now US 50 and Alternate US 50). Fernley northeast to Winnemucca, routed concurrently with US 40, (since replaced by I-80). Winnemucca north to the Idaho state line, replacing SR 8. In 1960, US 95 was realigned north of Fallon, replacing SR 1A and providing a more direct route to US 40 and Winnemucca. This eliminated the need to drive west to Fernley and then double back to the northeast. The former route via Fernley became Alternate US 95 (later renumbered as Alternate US 50 between Fallon and Fernley.

Around 1982, US 95 was realigned in western Las Vegas. Initially, US 95 entered downtown Las Vegas on Fremont Street and then turned north on Las Vegas Boulevard, west on Bonanza Road and followed Rancho Drive (formerly Tonopah Highway) in a northwesterly direction out of the city. Upon completion of the Oran K. Gragson Expressway (then known as the Las Vegas Expressway) in 1982 between downtown and Rancho Drive northwest of the city (at present-day exit 90), the route was shifted to the current alignment. The former route on Rancho Drive became Business US 95 and is now part of SR 599, while the Bonanza Road section is now SR 579.

The first section of the future I-515 freeway in Las Vegas opened from I-15 to Charleston Boulevard in 1984 and to Boulder Highway (at current exit 70) by 1985. US 95 was moved from the Las Vegas Boulevard, Fremont Street, and Boulder Highway onto the new freeway. As additional sections of freeway were completed, both US 95 and the concurrently routed US 93 were moved to the new facility. The I-515 designation was added with the completion of the entire freeway to Railroad Pass around 1995. The former route on Boulder Highway is now SR 582.
