The county is named for Doña Ana Robledo, who died there in 1680 while fleeing the Pueblo Revolt. Doña Ana County is one of only two counties in the United States to have a diacritical mark in its name, the other being Coös County, New Hampshire. Notably, both Doña Ana County and Coös County lie on short international borders, the former with Mexico and the latter with Canada.
Doña Ana County consists of the Las Cruces, NM Metropolitan Statistical Area, which is also included in the El Paso–Las Cruces, TX–NM Combined Statistical Area. It borders Luna, Sierra, and Otero counties in New Mexico, and El Paso County, Texas to the east and southeast.
The state of Chihuahua, Mexico, borders the county to the south. Construction of an improved barrier on the border was expedited in 2019 with waivers of environmental and other laws. The waivers applied to 27 laws, including protection of endangered species, archaeological sites, and historic places.
Being 67.3% Hispanic in 2020, Doña Ana is New Mexico's largest majority-Hispanic county.
