The county encompasses a diverse array of communities, from rural villages to agricultural lands.
Historical Background of the County
The name Doña Ana honors a Piro woman who died in the area in the 1680s. The county was established in 1852, shortly after the New Mexico Territory was organized. Its long history includes periods of Spanish colonial administration, Mexican governance, and eventual integration into the United States following the Treaty of Guadalupe Hidalgo.

Las Cruces functions as the county seat, hosting the primary government offices for Doña Ana County. The county operates under a commission-manager system. Residents of Las Cruces elect commissioners who oversee the county budget, infrastructure projects, and local ordinances that affect the entire region.
Economic and Cultural Impact
New Mexico State University is the largest employer in the area, anchoring the economy and providing a steady influx of students and faculty.

This blend creates a unique cultural tapestry visible in local festivals, cuisine, and arts.
Distinguishing Las Cruces from Other Locations
It is common for people to confuse this region with other states or counties due to the name "Cruz." However, Las Cruces is unequivocally part of New Mexico and specifically Doña Ana County.
