This is a list of the 33 counties in the U.S. state of New Mexico. There were originally nine counties formed in 1852. Santa Ana County, New Mexico Territory, one of the nine original counties, was annexed in 1876 to Bernalillo County, New Mexico.

The Federal Information Processing Standard (FIPS) code, which is used by the United States government to uniquely identify states and counties, is provided with each entry. New Mexico's code is 35, which when combined with any county code would be written as 35XXX. The FIPS code for each county links to census data for that county.
