List of counties in New Mexico

There are 33 counties in the U.S. state of New Mexico. First there were nine counties formed in 1852.

The Federal Information Processing Standard (FIPS) code, used by the United States government to uniquely identify states and counties, is provided with each entry.[1] New Mexico's code is 35. When added with any county code it would be written as 35XXX. The FIPS code for each county links to census data for that county.
