Homolovi State Park, Archaeological site and state park in Winslow, United States.

Homolovi State Park covers about 18 km² just north of Winslow, Arizona, and holds over 300 Ancestral Puebloan sites along the Little Colorado River floodplain. Seven pueblo ruins stand here, built between roughly 1260 and 1400; Homolovi II, the largest, has about 1,200 rooms, three rectangular plazas and some forty kivas. Petroglyphs can be seen along the Tsu'vo trail.

Several pueblo communities grew between 1260 and 1400, forming a network of settlements with some structures containing up to 1200 rooms. This flourishing period ended when residents eventually left the region and relocated elsewhere.

The Hopi word Homol'ovi means "place of the little hills." The Hopi tribe lobbied the Arizona parks board to drop "Ruins" from the park name, since they consider the villages spiritually alive; the board voted on March 17, 2011, to rename it and add the tagline "ancestral Hopi villages." The people of 1260–1400 are called Hisat'sinom, Hopi for "long-ago people."

The park offers trails for walking, a visitor center with exhibits, and guided programs throughout the year. Plan for several hours to explore, and bring water since the area is exposed and can be warm.

Residents grew cotton here and traded their harvest for pottery and other goods with Hopi communities at the mesas. These trading routes show how connected the different pueblos were across the region.
