Durango (Spanish pronunciation: [duˈɾaŋɡo], Southeastern Tepehuan: Korian) is the capital and largest city of the northern Mexican state of Durango and the seat of the municipality of Durango. It has a population of 616,068 as of the 2020 census with 688,697 living in the municipality. The city's official name is Victoria de Durango, renamed in honor of the first president of Mexico, Guadalupe Victoria, a native of the state of Durango. The city is at an altitude of 1,890 m (6,201 ft) in the Valley of Guadiana.

Durango was founded on 8 July 1563, by the Spanish explorer Francisco de Ibarra. During the Spanish colonial era the city was the capital of the Nueva Vizcaya province of New Spain, which consisted mostly of what became the Mexican states of Durango and Chihuahua. The city was founded due to its proximity to the Cerro del Mercado, in the northern part of the modern city, which was believed to contain large amounts of silver. Eventually, an important iron deposit was discovered.

The town was named by Francisco de Ibarra after his hometown Durango in the Spanish province of Biscay. The name Durango is of Basque origin. Ibarra also named the surrounding area Nuevo Vizcaya (New Biscay). The official name of the city became Victoria de Durango in 1826, in honor of Guadalupe Victoria, the first president of Mexico and native of the state. The city's coat-of-arms serves as the seal for the state.

Since the pre-historic period the area was a conduit for influences from north and south, between Aridoamerica and Mesoamerica. The first inhabitants of the area were a people called the Nahoas, nomads who came to the area from the north about 2,000 years ago. By the Post Classic period, the area became inhabited by the Zacatecans and the Tepehuanos, who migrated here from the north-west.

The modern city began as a mining town, officially founded as Villa de Durango by Francisco de Ibarra on 8 July 1563. Ibarra was sent north by Viceroy Luis de Velasco to conquer the territory and found the city. The site was chosen because of its proximity to the Cerro de Mercado, thought at the time to contain reserves of silver, but instead was found to be an important source of iron. The mountain was named for Captain Ginés Vázquez de Mercado, who discovered the valley on his expeditions in the north. The site was also chosen because it was close to the Franciscan mission at Analco, which was a source of water, wood, and animals to hunt. The initial layout of the town was done by Alonso de Pacheco, bordered by what became Madero and Constitución streets on running north–south, and by 5 February and 20 November running east–west. The historic center is located around the Plaza de Armas (main square) and the Cathedral Basilica.

Due to its distance from Mexico City, the city and the surrounding communities developed relatively autonomously. Some of the earliest missions in the north of the country are located in and around the city. It became an important stop on the road north to conquer what is now the north of Mexico and Southwest U.S. The Jesuits were also missionaries here from 1596 until their expulsion from New Spain in 1767. They founded the Colegio de Guadiana, which was the main educational institution for northern Mexico during the colonial period.

The town became a parish in 1620. It was officially named a city on 3 March 1630. Difficulties forced the near-abandonment of the city of Durango in the 17th century, with the provincial capital moving to Parral, but starting in 1680, the city began to grow again. This was because the mines in Parral had started to give out and the reduction in violence as the Spanish government succeeded in subduing the native peoples. The city regained its role as the province's capital on 10 October 1738.

Durango provided peak influence during the 18th century because of the mining of various minerals in the nearby Sierra Madre Occidental. The bonanza allowed for the creation of several grand colonial-era buildings in the city center.
