Jean is a small commercial town in Clark County, Nevada, United States, located approximately 12 mi (19 km) north of the Nevada–California state line along Interstate 15. Las Vegas is located about 30 mi (48 km) to the north. There are no residents of Jean, but many people in nearby communities such as Primm and Sandy Valley have Jean listed in their mailing address because it is the location of the main post office for the 89019 ZIP code. South Las Vegas Boulevard ends about 2 mi (3.2 km) south of Jean, and it contiguously runs northbound past Las Vegas, ending near the I-15–US 93 Junction.
The area is mostly commercial, with the exception of the post office and the courthouse, with commercial outlets such as Terrible's Hotel & Casino, the Jean Sport Aviation Center (used for activities like skydiving), Jean Conservation Camp (a minimum-security, all female Nevada Department of Corrections facility established in 1987) and a Nevada Highway Patrol (NHP) substation. The Nevada Landing Hotel and Casino was also located here but it was demolished in April 2008 and the sign was removed in 2010. The Jean Post Office is located on Las Vegas Boulevard in Jean. The Goodsprings Township Courthouse is also located in Jean.
The town was originally named Goodsprings Junction. On June 28, 1905, postmaster George Arthur Fayle renamed it Jean in honor of his wife.
