Bernalillo County was one of seven partidos established during Mexican rule; in 1852, within two years of the creation of the New Mexico Territory, Bernalillo became one of that territory's nine original counties.[1] Bernalillo County was named for the town of Bernalillo, which is currently no longer part of the county.[4] The towns of Los Ranchos de Albuquerque and Bernalillo were previously the county seats, but the capital was finally established in Albuquerque in 1883.[5] In 1876, it absorbed Santa Ana County.
According to the U.S. Census Bureau, the county has a total area of 1,167 square miles (3,020 km2), of which 1,161 square miles (3,010 km2) is land and 6.4 square miles (17 km2) (0.5%) is water.[7] It is the third-smallest county in New Mexico by area.
Bernalillo County is in central New Mexico, and "stretches from the East Mountain area (just east of the Sandia Mountains) to the Volcano Cliffs on the west mesa."[8]

A local toponymic oddity is that the town of Bernalillo, north of Albuquerque, is not actually in Bernalillo County. When established in 1852, the county was named for the town of Bernalillo, which was incorporated into Sandoval County in 1903.[4][19]
