Guadalupe County (Spanish: Condado de Guadalupe) is a county in the U.S. state of New Mexico. As of the 2020 census, the population was 4,452.^[1] Its county seat is Santa Rosa.^[2]

Guadalupe County was named after Nuestra Señora de Guadalupe (Our Lady of Guadalupe) or after the Mesita de Guadalupe (Guadalupe Plain). The county was created from the southern portion of San Miguel County February 26, 1891, by an act of the New Mexico Territorial Legislature. The original county seat was Puerto De Luna, but was moved north to Santa Rosa in 1903. That same year, after the popular Spanish–American War of 1898, the county's name was changed to Leonard Wood County after the Presidential physician, Major-General in the Rough Riders, and recipient of the Medal of Honor. The name was later changed back to Guadalupe County.^[3] The County contains whole, or parts of, several previous Spanish land grants to include the Aqua Negra, the Jose Perea, the Anton Chico, and the Preston Beck land grants.^[4]

According to the U.S. Census Bureau, the county has a total area of 3,032 square miles (7,850 km²), of which 3,030 square miles (7,800 km²) is land and 1.1 square miles (2.8 km²) (0.04%) is water.^[5]

Guadalupe County leans Democratic, and has voted for the Democratic nominee in every presidential election since 1988. In 2024, however, Guadalupe County saw a trend toward the Republican Party in line with majority-Hispanic counties nationally when Donald Trump came within less than 1% of flipping it, with Kamala Harris holding it by a plurality and winning by only 14 votes. This was the best performance for a Republican in the county since Reagan won it in 1984.

The county has two school districts serving sections: Santa Rosa Consolidated Schools and Vaughn Municipal Schools.^[17]
