The Pueblo IV period (1350–1600) was the fourth period of the Ancestral Puebloans in Oasisamerica. At the end of prior Pueblo III period, ancestral Puebloans living in the Colorado and Utah regions abandoned their settlements and migrated south to the Pecos River and Rio Grande valleys. As a result, pueblos in those areas saw a significant increase in total population.
The Pueblo IV period (Pecos Classification) is similar to the "Regressive Pueblo period" or, referring to the Ancestral Puebloans of Colorado and Utah, the "post-Pueblo period." It is preceded by Pueblo III and is followed by the present Pueblo V period.
