South Valley is a census-designated place (CDP) and unincorporated community in Bernalillo County, New Mexico, United States.

Postal Service uses "Albuquerque" for all South Valley addresses (ZIP code 87105).

The South Valley is located in central Bernalillo County and is bordered on the north, east, and half of its west side by the city of Albuquerque.

In January 2010, a special election was held in the South Valley to decide whether or not the region should incorporate into a city, to be named Valle de Atrisco.

[8] Voters in the South Valley overwhelmingly rejected incorporation by a 93 to 7 percent margin during the special election on January 5, 2010.

Opponents to incorporation cited the potential costs (and tax burden for residents) for providing for education, public works, police and fire services in the South Valley because Bernalillo County would no longer be providing these services to the community following incorporation.

[9] Supporters argued in favor of incorporation to protect the community from possible annexation into the City of Albuquerque, and the potential for increased taxes and perceived degradation of public services that would arise from being integrated into the city.
