Pueblo del Arroyo, Ancient house in Chaco Culture National Historical Park, New Mexico, United States.

Pueblo del Arroyo is a large ruin with approximately 300 rooms arranged in a D-shaped floor plan, representing a complex residential community. The structure ranks as one of the four largest great houses constructed in Chaco Canyon and demonstrates careful architectural design.

Construction of this settlement began around 1060 and expanded over several decades into a major community. Systematic archaeological excavations in the 1920s revealed the layout and details of the site that visitors see today.

Fourteen kivas have been identified at Pueblo del Arroyo, but no great kiva was ever found there, unlike at neighbouring Pueblo Bonito. The round, sunken chambers served as ceremonial rooms for the community. Visitors can pick out their stone-lined depressions among the room blocks.

Pueblo del Arroyo sits a few hundred yards from Pueblo Bonito, near Chaco Wash and opposite South Gap. The site is reached from the Canyon Loop Drive; the trail is short and level. There is no shade or shelter, so carry water and prepare for desert conditions.

Pueblo del Arroyo has fourteen kivas but no great kiva, unlike the other great houses of Chaco Canyon. Archaeologist Neil Judd, who dug about half the site between 1923 and 1926, thought a group from crowded Pueblo Bonito built it. It lies mid-canyon facing east, opposite South Gap.
