Luna County (Spanish: Condado de Luna) is a county located in the U.S. state of New Mexico. As of the 2020 census, the population was 25,427.^[1] Its county seat is Deming.^[2] This county abuts the Mexican border. Luna County comprises the Deming, NM Micropolitan Statistical Area.

Luna County was formed from parts of Grant County and Doña Ana County by the New Mexico Legislature on March 16, 1901. It was named for Solomon Luna, a politician who advocated for independence of the county, following a strong rivalry between the cities of Deming and Silver City, both of which were at the time in Grant County.^[3]

Before dawn on March 16, 1916, Mexican revolutionary Pancho Villa led several hundred of his rebel soldiers across the Mexican border into the village of Columbus in the southern part of the county. The invaders raided and burned much of the town, causing many residents to flee to the desert. Although the raid took the town by surprise, it also awakened 350 United States Army soldiers stationed at Camp Furlong at the edge of town. These soldiers defended Columbus with two machine guns. The fighting continued until dawn, when Villa fled back across the Mexican border, five hours after the initial invasion and approximately ninety minutes after attacking the town. Despite the U.S. Army's subsequent "Mexican Expedition" into Mexico, Villa was never captured. The United States' involvement in World War I soon diverted attention away from the pursuit of Villa. He was assassinated seven years later. The raid resulted in the deaths of eighteen Columbus residents and U.S. soldiers, while approximately seventy-five of Villa's soldiers were killed.

In 1917 striking copper miners from Bisbee, Arizona were forcibly deported to this county.

Construction of an improved barrier on the border with Mexico 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.^[4]

Today, Pancho Villa State Park is located in the village of Columbus. It features cacti and the ruins of "the U.S. Army's first greaserack".

According to the U.S. Census Bureau, the county has a total area of 2,965 square miles (7,680 km²), virtually all of which is land.^[5] The bulk of the county is flat lowland, either grassland or desert scrub, but it also contains three mountain ranges: Cooke's Range in the north, the Florida Mountains on the southeastern side of Deming near the center of the county, and the Tres Hermanas Mountains in the southern part of the county near Columbus.
