Albuquerque, abbreviated as ABQ, is the most populous city in the U.S. state of New Mexico. Its nicknames, The Duke City and Burque, both reference its 1706 founding by Nuevo México governor Francisco Cuervo y Valdés as La Villa de Alburquerque. Named in honor of the Viceroy of New Spain, the 10th Duke of Alburquerque, the city was an outpost on El Camino Real linking Mexico City to the northernmost territories of New Spain. The 2020 census found the population of the city to be 564,559, making Albuquerque the 32nd-most populous city in the United States and the fourth-largest in the Southwest. It is the principal city of the Albuquerque metropolitan area, which had 916,528 residents as of July 2020.
Located in north-central New Mexico, Albuquerque serves as the county seat of Bernalillo County. To its east are the Sandia–Manzano Mountains, Rio Grande flows north to south through its center, while the West Mesa and Petroglyph National Monument make up the western part of the city.
