Pueblo refers to the settlements of the Pueblo peoples, Native American tribes in the Southwestern United States, currently in New Mexico, Arizona, and Texas. The permanent communities, including some of the oldest continually occupied settlements in the United States, are called pueblos (lowercased).

Spanish explorers of northern New Spain used the term pueblo to refer to permanent Indigenous towns they found in the region, mainly in New Mexico and parts of Arizona, in the former province of Nuevo México. This term continued to be used to describe the communities housed in apartment structures built of stone, adobe, and other local material. The structures were usually multistoried buildings surrounding an open plaza. Many rooms were accessible only through ladders raised and lowered by the inhabitants, thus protecting them from break-ins and unwanted guests. Larger pueblos are occupied by hundreds to thousands of Puebloan people.

Several federally recognized tribes have historically resided in pueblos of such design. Later Pueblo Deco and modern Pueblo Revival architecture, which mixes elements of traditional Pueblo and Hispano design, has continued to be a popular architectural style in New Mexico, expanding to surrounding states over time.

The term is part of the official name of some historical sites, such as Pueblo of Acoma.

The word pueblo is the Spanish word both for "town" or "village" and for "people". It comes from the Latin root word populus meaning "people". Spanish colonials applied the term to their own civic settlements, but to only those Native American settlements having fixed locations and permanent buildings.

In the Rio Grande Valley of New Mexico, specifically in the region between Albuquerque, Santa Fe and Taos, the word "pueblo" defines a "distinct cultural group in the Southwestern United States" and their villages. The Holmes Museum of Anthropology defines this specific group as a "common culture with individual variances [that] connects them.

Less-permanent Native settlements (such as those found in California) were often referred to as rancherías, however, the oldest area of Los Angeles was known as El Pueblo de Nuestra Señora la Reina de los Ángeles del Rio de Porciúncula or El Pueblo de Los Angeles for short.

On the central Spanish Meseta the unit of settlement was and is the pueblo; which is to say, the large nucleated village surrounded by its own fields, with no outlying farms, separated from its neighbors by some considerable distance, sometimes as much as ten miles [16 km] or so. The demands of agrarian routine and the need for defense, the simple desire for human society in the vast solitude of (rocky plains, or the desert), dictated that it should be so. Nowadays the pueblo might have a population running into thousands. Doubtless, they were much smaller in the early middle ages, but we should probably not be far wrong if we think of them as having had populations of some hundreds.
