Its county seat is Las Cruces, the second-most populous municipality in New Mexico after Albuquerque, with 111,385 as of the 2020 U.S. Census.
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.

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 are for 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.
