Albuquerque is the largest city in the state of New Mexico, United States. It is situated in the central part of the state, straddling the Rio Grande. The city population was 518,271 as of the July 1, 2007 U.S. census estimates with a metropolitan population of 835,120.

The city was founded in 1706 as the Spanish colonial outpost of Ranchos de Alburquerque; present-day Albuquerque retains much of the Spanish cultural and historical heritage. Albuquerque was a farming community and strategically located military outpost along the Camino Real. The town of Alburquerque was built in the traditional Spanish village pattern: a central plaza surrounded by government buildings, homes, and a church. This central plaza area has been preserved and is open to the public as a museum, cultural area, and center of commerce. It is referred to as "Old Town Albuquerque" or simply "Old Town."

On June 2007 Albuquerque was listed as the 6th fastest growing city in America by CNN and the US Census Bureau. Albuquerque's downtown entered the same phase and development (decline, "urban renewal" with continued decline, and gentrification) as nearly every city across the United States. As Albuquerque spread outward, the downtown area fell into a decline. Many historic buildings were razed in the 1960s and 1970s to make way for new plazas, high-rises, and parking lots as part of the city's urban renewal phase. Only recently has downtown come to regain much of its urban character, mainly through the construction of many new loft apartment buildings and the renovation of historic structures like the KiMo Theater, in the gentrification phase.

Albuquerque lies at the center of the New Mexico Technology Corridor, a concentration of high-tech private companies and government institutions along the Rio Grande. Larger institutions whose employees contribute to the population are numerous and include Sandia National Laboratories, Kirtland Air Force Base, and the attendant contracting companies which bring highly educated workers to a somewhat isolated region. Intel operates a large semiconductor factory or "fab" just outside the city boundaries of suburban Rio Rancho, in neighboring Sandoval County, with its attendant large capital investment.

Urban sprawl is limited on three sides by the Pueblo of Sandia to the north, the Pueblo of Isleta and Kirtland Air Force Base to the south, and the Sandia Mountains to the east. Suburban growth continues at a strong pace to the west beyond the Petroglyph National Monument, once thought to be a natural boundary to sprawl development.
