Not to be confused with Mesa Grande Band of Diegueno Mission Indians.

Mesa Grande ruins, in Mesa, Arizona, preserves a group of Hohokam structures constructed during the classical period. The ruins were occupied between AD 1100 and 1400 (Pueblo II - Pueblo IV Era) and were a product of the Hohokam civilization that inhabited the Salt River Valley. There the Hohokam constructed an extensive system of water canals before vanishing for mysterious reasons. It is one of only two remaining Hohokam mounds remaining in the metro Phoenix area, with the other being the Pueblo Grande Museum Archaeological Park. The site's central feature is a massive ruin of adobe walls and platforms.^[2]^[3]

It was listed on the National Register of Historic Places in 1978^[1] when it was owned by B-movie actress Acquanetta. The site was acquired from her in 1988 by the city of Mesa.^[4]

At the present time, the ruin is not open to the public but can be seen through the fence. The Arizona Museum of Natural History is currently undertaking archaeological studies at the site, and is working on opening it to the public.^[5] The mound remains remarkably intact. The general site remains protected but undeveloped.

The ruins are located to the west and across the street from the former Mesa Lutheran Hospital, now a Banner Health corporate center housing billing and Information Technology employees.

Artifacts presumably associated with the ruins have been found in the neighborhood to the west. Axe heads, arrow heads, and pottery sherds were regularly uncovered and collected by residents during the 1960s and 1970s just under the surface of the earth in private property there.^{[citation needed]}
